God: there is no god but Him, the Ever Living, the Ever Watchful.Neither slumber nor sleep overtakes Him. All that is in the heavens and in the earth belongs to Him. Who is there that can intercede with Him except by His leave? He knows what is before them and what is behind them, but they do not comprehend any of His knowledge except what He wills. His throne extends over the heavens and the earth; it does not weary Him to preserve them both. He is the Most High, the Tremendous

After sorrow, He caused calm to descend upon you, a sleep that overtook some of you. Another group, caring only for themselves, entertained false thoughts about God, thoughts more appropriate to pagan ignorance, and said, ‘Do we get a say in any of this?’ [Prophet], tell them, ‘Everything to do with this affair is in God’s hands.’ They conceal in their hearts things they will not reveal to you. They say, ‘If we had had our say in this, none of us would have been killed here.’ Tell them, ‘Even if you had resolved to stay at home, those who were destined to be killed would still have gone out to meet their deaths.’ God did this in order to test everything within you and in order to prove what is in your hearts. God knows your innermost thoughts very well
فَالِقُ ٱلۡإِصۡبَاحِ وَجَعَلَ ٱلَّيۡلَ سَكَنࣰ ا وَٱلشَّمۡسَ وَٱلۡقَمَرَ حُسۡبَانࣰ اۚ ذَٰلِكَ تَقۡدِيرُ ٱلۡعَزِيزِ ٱلۡعَلِيمِ
He makes the dawn break; He makes the night for rest; and He made the sun and the moon to a precise measure. That is the design of the Almighty, the All Knowing
إِذۡ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةࣰ مِّنۡهُ وَيُنَزِّلُ عَلَيۡكُم مِّنَ ٱلسَّمَآءِ مَآءࣰ لِّيُطَهِّرَكُم بِهِۦ وَيُذۡهِبَ عَنكُمۡ رِجۡزَ ٱلشَّيۡطَٰنِ وَلِيَرۡبِطَ عَلَىٰ قُلُوبِكُمۡ وَيُثَبِّتَ بِهِ ٱلۡأَقۡدَامَ
Remember when He gave you sleep as a reassurance from Him, and sent down water from the sky to cleanse you, to remove Satan’s pollution from you, to make your hearts strong and your feet firm
Commentary on the verses above, at most two editions per verse.
And He it is Who made for you the night as a garment veiling you like a garment and sleep for repose rest for bodies through the temporary cessation of labour and He made the day for rising a time in which all rise to seek their livelihood and so on.
Have you not seen how your Lord spread the shadow. If He willed, He could have made it still – but We have made the sun its guide (45)Then We withdraw it towards Ourselves – a gradual withdrawal (46)And it is He Who makes the night a covering for you, and the sleep (as) a repose, and makes the day Nushur (47) Evidence of the Existence of the Creator and the Extent of His Power Here Allah begins explaining the evidence for His existence and His perfect power to create various things and pairs of opposites. Allah says: أَلَمْ تَرَ إِلَىٰ رَبِّكَ كَيْفَ مَدَّ الظِّلَّ (Have you not seen how your Lord spread the shadow.) Ibn 'Abbas, Ibn 'Umar, Abu Al-'Aliyah, Abu Malik, Masruq, Mujahid, Sa'id bin Jubayr, An-Nakha'i, Ad-Dahhak, Al-Hasan, Qatadah, As-Suddi and others said, "This refers to the period from the beginning of the dawn until the sun rises." وَلَوْ شَاءَ لَجَعَلَهُ سَاكِنًا (If
God there is no god that is there is none worthy of being worshipped in all existence except Him the Living the Everlasting the Eternal Sustainer the One constantly engaged in the management of His creation. Slumber does not seize Him neither sleep; to Him belongs all that is in the heavens and the earth as possessions creatures and servants; who is there that is to say none is there that shall intercede with Him save by His leave? in this for him. He knows what lies before them that is creation and what is after them of the affairs of this world and the Hereafter; and they encompass nothing of His knowledge that is they know nothing of what He knows save such as He wills to inform of it by way of His messengers. His throne subsumes the heavens and the earth it is said that His knowledge encompasses them both; it is also said that the kursī ‘throne’ itself subsumes them on account of its
and made your sleep for rest? repose for your bodies
Allah! None has the right to be worshipped but He, the Ever Living, the One Who sustains and protects all that exists. Neither slumber nor sleep overtakes Him. To Him belongs whatever is in the heavens and whatever is on the earth. Who is he that can intercede with Him except with His permission? He knows what happens to them (His creatures) in this world, and what will happen to them in the Hereafter. And they will never compass anything of His Knowledge except that which He wills. His Kursi extends over the heavens and the earth, and He feels no fatigue in guarding and preserving them. And He is the Most High, the Most Great (255) The Virtue of Ayat Al-Kursi This is Ayat Al-Kursi and tremendous virtues have been associated with it, for the authentic Hadith describes it as 'the greatest Ayah in the Book of Allah.' Imam Ahmad recorded that 'Ubayy bin Ka'b said that the Prophet ﷺ asked

Abu Hurairah narrated that the Messenger of Allah (s.a.w) said:"When time draws near, the dreams of a believer will hardly ever fail to come true, and the most truthful of them in dreams will be the truest in speech among them. The dream of a Muslim is a portion among the forty-six portions of Prophet-hood. And dreams are of three types: The righteous dream which is good news from Allah, dreams in which the Shaithan frightens someone, and dreams about something that has happened to the man himself. So when one of you sees what he dislikes, then he should get up and spit, and not tell any of the people- he said:- and I like the fetters in a dream while I dislike the iron collar." And the interpretation of fetters is being firm in the religion

Narrated Um Salama:One night the Prophet (ﷺ) got up and said, "Subhan Allah! How many afflictions Allah has revealed tonight and how many treasures have been sent down (disclosed). Go and wake the sleeping lady occupants of these dwellings up (for prayers), perhaps a well dressed in this world may be naked in the Hereafter

Narrated Ibn Shihab:Once `Umar bin `Abdul `Aziz delayed the prayer and `Urwa bin Az-Zubair went to him and said, "Once in 'Iraq, Al-Mughira bin Shu`ba delayed his prayers and Abi Mas`ud Al-Ansari went to him and said, 'O Mughira! What is this? Don't you know that once Gabriel came and offered the prayer (Fajr prayer) and Allah's Messenger (ﷺ) prayed too, then he prayed again (Zuhr prayer) and so did Allah's Apostle and again he prayed (`Asr prayers and Allah's Messenger (ﷺ) did the same; again he prayed (Maghrib-prayer) and so did Allah's Messenger (ﷺ) and again prayed (`Isha prayer) and so did Allah's Apostle and (Gabriel) said, 'I was ordered to do so (to demonstrate the prayers prescribed to you)?'" `Umar (bin `Abdul `Aziz) said to `Urwa, "Be sure of what you Say. Did Gabriel lead Allah's Messenger (ﷺ) at the stated times of the prayers?" `Urwa replied, "Bashir bin Abi Mas`ud narrated like this on the authority of his father." `Urwa added, "Aisha told me that Allah's Messenger (ﷺ) used to pray `Asr prayer when the sunshine was still inside her residence (during the early time of `Asr)

Narrated Ibn `Abbas:"Once a delegation of `Abdul Qais came to Allah's Messenger (ﷺ) and said, "We belong to such and such branch of the tribe of Rabi'ah and we can only come to you in the sacred months. Order us to do something good so that we may take it from you and also invite to it those whom we have left behind (at home)." So he said, "I order you to do four things and forbid you from four things: To believe in Allah" - and then he explained it to them "to testify that none has the right to be worshipped but Allah and that I am Allah's Messenger (ﷺ), to establish the prayers (at the stated times), to pay the Zakat (obligatory charity), to hand me the Khumus (fifth) if you acquire spoils of war. And I forbid from (using) Dubba, Hantam, Muqaiyyar, and Naqir (all these were utensils used for the preparation of alcoholic drinks)

Sleep and sleep disorders in children and adolescents.
Pediatric sleep disorders are common, affecting approximately 25% to 40% of children and adolescents. Although there are several different types of sleep disorders that affect youth, each disorder can have a significant impact on daytime functioning and development, including learning, growth, behavior, and emotion regulation. Researchers are only beginning to uncover the interaction between sleep and psychiatric disorders in children and adolescents, including depression, attention-deficit/hyperactivity disorder, and autism. This article reviews normal sleep and sleep disorders in children and adolescents, the assessment of sleep in pediatric populations, common pediatric sleep disorders, and sleep in children who have common psychiatric disorders.

Insomnia disorder in adolescence: Diagnosis, impact, and treatment.
Insomnia disorder is very common in adolescents; it is particularly manifest in older adolescents and girls, with a prevalence comparable to that of other major psychiatric disorders (e.g., depressive disorders). However, insomnia disorder in adolescence is poorly characterized, under-recognized, under-diagnosed, and under-treated, and the reason for the female preponderance for insomnia that emerges after puberty is largely unknown. Insomnia disorder goes beyond an individual complaint of poor sleep or a sleep state misperception, and there is emerging evidence supporting the association of insomnia symptoms in adolescents with alterations in several bio-systems including functional cortical alterations and systemic inflammation. Insomnia disorder is associated with depression and other psychiatric disorders, and is an independent risk factor for suicidality and substance use in adolesc…

Internight sleep variability: its clinical significance and responsiveness to treatment in primary and comorbid insomnia.
Although sleep diary and actigraphy data are usually collected daily for 1 or 2 weeks, traditional analytical approaches aggregate these data into mean values. Internight variability of sleep often accompanies insomnia. However, few studies have explored the relevance of this 'construct' in the context of diagnosis, clinical impact, treatment effects and/or whether having 'variable sleep' carries any prognostic significance. We explored these questions by conducting secondary analyses of data from a randomized clinical trial. The sample included primary (PI: n = 40) and comorbid insomnia (CMI: n = 41) sufferers receiving four biweekly sessions of cognitive-behavioural therapy (CBT) or sleep hygiene education. Using the within-subject standard deviations of diary- and actigraphy-derived measures collected for 2-week periods [sleep onset latency (SOL), wake after sleep onset (WASO), total …

Sleep Deprivation and Circadian Disruption Stress, Allostasis, and Allostatic Load.
Getting a good night's sleep seems a panacea for improving mood and cognition. These subjective impressions are supported by countless studies exploring the impacts of sleep (and sleep loss) on mental health, metabolism, and immune function. Similarly, being "out of phase" with local time, commonly experienced by shift workers of jet-lagged air travelers, demonstrates that there are both neural and physiologic effects of internal circadian (daily) time being misaligned with external environmental time. This article reviews these areas contextualized using the model of allostasis and allostatic load emphasizing the impact of this "wear and tear" on the brain and body.

Sleep Loss and the Socio-Emotional Brain.
Are you feeling emotionally fragile, moody, unpredictable, even ungenerous to those around you? Here, we review how and why these phenomena can occur as a result of insufficient sleep. Sleep loss disrupts a broad spectrum of affective processes, from basic emotional operations (e.g., recognition, responsivity, expression), through to high-order, complex socio-emotional functioning (e.g., loneliness, helping behavior, abusive behavior, and charisma). Translational insights further emerge regarding the pervasive link between sleep disturbance and psychiatric conditions, including anxiety, depression, and suicidality. More generally, such findings raise concerns regarding society's mental (ill)health and the prevalence of insufficient and disrupted sleep.

Sex differences in sleep and sleep loss-induced cognitive deficits: The influence of gonadal hormones.
Males and females can respond differentially to the same environmental stimuli and experimental conditions. Chronic sleep loss is a frequent and growing problem in many modern societies and has a broad variety of negative outcomes for health and well-being. While much has been done to explore the deleterious effects of sleep deprivation (SD) on cognition in both human and animal studies over the last few decades, very little attention has been paid to the part played by sex differences and gonadal steroids in respect of changes in cognitive functions caused by sleep loss. The effects of gonadal hormones on sleep regulation and cognitive performances are well established. Reduced gonadal function in menopausal women and elderly men is associated with sleep disturbances and cognitive decline as well as dementia, which suggests that sex steroids play a key role in modulating these condition…

The role of sleep in regulating structural plasticity and synaptic strength: Implications for memory and cognitive function.
Dendritic spines are the major sites of synaptic transmission in the central nervous system. Alterations in the strength of synaptic connections directly affect the neuronal communication, which is crucial for brain function as well as the processing and storage of information. Sleep and sleep loss bidirectionally alter structural plasticity, by affecting spine numbers and morphology, which ultimately can affect the functional output of the brain in terms of alertness, cognition, and mood. Experimental data from studies in rodents suggest that sleep deprivation may impact structural plasticity in different ways. One of the current views, referred to as the synaptic homeostasis hypothesis, suggests that wake promotes synaptic potentiation whereas sleep facilitates synaptic downscaling. On the other hand, several studies have now shown that sleep deprivation can reduce spine density and at…

Sleep deprivation and hippocampal vulnerability: changes in neuronal plasticity, neurogenesis and cognitive function.
Despite the ongoing fundamental controversy about the physiological function of sleep, there is general consensus that sleep benefits neuronal plasticity, which ultimately supports brain function and cognition. In agreement with this are numerous studies showing that sleep deprivation (SD) results in learning and memory impairments. Interestingly, such impairments appear to occur particularly when these learning and memory processes require the hippocampus, suggesting that this brain region may be particularly sensitive to the consequences of sleep loss. Although the molecular mechanisms underlying sleep and memory formation remain to be investigated, available evidence suggests that SD may impair hippocampal neuronal plasticity and memory processes by attenuating intracellular cyclic adenosine monophosphate (cAMP)-protein kinase A (PKA) signaling which may lead to alterations in cAMP re…

REM sleep dysregulation in depression: state of the art.
Disturbances of sleep are typical for most depressed patients and belong to the core symptoms of the disorder. Since the 1960s polysomnographic sleep research has demonstrated that besides disturbances of sleep continuity, depression is associated with altered sleep architecture, i.e., a decrease in slow wave sleep (SWS) production and disturbed rapid eye movement (REM) sleep regulation. Shortened REM latency (i.e., the interval between sleep onset and the occurrence of the first REM period), increased REM sleep duration and increased REM density (i.e., the frequency of rapid eye movements per REM period) have been considered as biological markers of depression which might predict relapse and recurrence. High risk studies including healthy relatives of patients with depression demonstrate that REM sleep alterations may precede the clinical expression of depression and may thus be useful …

Stress hormones, sleep deprivation and cognition in older adults.
Cognition can be deteriorated in older persons because of several potential mechanisms including the hormonal changes occurring with age. Stress events cause modification in hormonal balance with acute and chronic changes such as increase in cortisol and thyroid hormones, and simultaneous alterations in dehydroepiandrosterone sulphate, testosterone and insulin like growth factor-1 levels. The ability to cope with stress and regain previous healthy status, also called resiliency, is particularly impaired in older persons Thus, stressful conditions and hormonal dysregulation might concur to the onset of cognitive impairment in this population. In this review we address the relationship between stress hormones and cognitive function in older persons focusing on the role of one of the main stress factors, such as sleep deprivation (SD). We extracted and cross-checked data from 2000 to 2013 M…

Association between Chronotype and Sleep Quality among Chinese College Students: The Role of Bedtime Procrastination and Sleep Hygiene Awareness.
Chronotype and sleep quality have been shown to play significant roles in influencing people's physical and mental health. The current study focuses on examining the relationship between chronotype and sleep quality among Chinese college students and exploring the mediating role of bedtime procrastination and the moderating role of sleep hygiene awareness. A sample of 2822 college students (female = 71.4%) aged between 17 and 29 years (M = 19.77, SD = 1.41) were included and completed the measures of the Pittsburgh Sleep Quality Index (PSQI), Morningness-Eveningness Questionnaire (MEQ), Bedtime Procrastination Scale (BPS) and Sleep Hygiene Awareness Scale (SHAS). The results showed that evening-type students reported the lowest sleep quality and highest levels of bedtime procrastination. In contrast, the highest sleep quality and lowest levels of bedtime procrastination were shown by mor…

Objective and subjective socioeconomic gradients exist for sleep in children and adolescents.
Objective: Socioeconomic position (SEP) is inversely associated with many health outcomes, yielding a socioeconomic gradient in health. In adults, low SEP is associated with short sleep duration, poorer sleep quality, and difficulty initiating and maintaining sleep. Relatively little is known about this relation in youth. The aim of the present study was to examine whether socioeconomic gradients exist for various sleep indices among a healthy sample of children and adolescents. Method: Participants took part in the larger Healthy Heart Project and included 239 youth (69.6% Caucasian; 45.6% female), aged 8-17 years (M = 12.6, SD = 1.9). Parental income and education were used to measure objective SEP. The Subjective Social Status Scale-Youth Version was used to measure subjective SEP. Sleep duration, sleep quality, daytime sleepiness, and sleep disturbances were assessed through self- an…

Telephone-based mindfulness training to reduce stress in women with myocardial infarction: Rationale and design of a multicenter randomized controlled trial.
Background: Elevated stress is associated with adverse cardiovascular disease outcomes and accounts in part for the poorer recovery experienced by women compared with men after myocardial infarction (MI). Psychosocial interventions improve outcomes overall but are less effective for women than for men with MI, suggesting the need for different approaches. Mindfulness-based cognitive therapy (MBCT) is an evidence-based intervention that targets key psychosocial vulnerabilities in women including rumination (i.e., repetitive negative thinking) and low social support. This article describes the rationale and design of a multicenter randomized controlled trial to test the effects of telephone-delivered MBCT (MBCT-T) in women with MI. Methods: We plan to randomize 144 women reporting elevated perceived stress at least two months after MI to MBCT-T or enhanced usual care (EUC), which each invo…

Non-pharmacological interventions for sleep disturbances in people with dementia.
Background: Sleep disturbances occur frequently in people with dementia with a reported prevalence of up to 40%. Common problems are increased number and duration of awakenings and increased percentage of light sleep. Sleep disturbances are associated with a number of problems for people with dementia, their relatives, and carers. In people with dementia, they may lead to worsening of cognitive symptoms, challenging behaviours such as restlessness or wandering, and further harms, such as accidental falls. Sleep disturbances are also associated with significant carer distress and have been reported as a factor contributing to institutionalisation of people with dementia. As pharmacological approaches have shown unsatisfactory results, there is a need to synthesise the research evidence on non-pharmacological strategies to improve sleep in people with dementia. As interventions are often c…

Risk and protective factors and processes for behavioral sleep problems among preschool and early school-aged children: A systematic review.
Behavioral sleep problems in early childhood are common, affecting about 25% of children, and include symptoms such as problems going to sleep and staying asleep. This review employed the developmental psychopathology framework and 4P model (Predisposing, Precipitating, Perpetuating, Protective) to organize the diverse risk/protective factors (distal variables experienced indirectly by the child) and processes (proximal variables experienced directly by the child) for child sleep problems among preschool (1-5 y) and school-age (6-10 y) children. Variables were categorized into biological, psychological, and environmental factors/processes at the individual, family/parent, and community levels. The quality of evidence was assessed using GRADE. A literature search identified 98 articles meeting inclusion criteria. Older child age, difficult temperament, previous sleep problems, externalizi…

Self-referral to group cognitive behavioural therapy: Is it effective for treating chronic insomnia?
Objectives: To evaluate the effectiveness of a short (3 session) programme of group cognitive behavioural therapy (CBT) on insomnia, sleepiness and symptoms of anxiety and depression. Methods: Prospective observational study of group CBT with follow-up at 3 months. Participants were self-referred patients with chronic insomnia. Outcome measures were the insomnia severity scale (ISI), the Epworth sleepiness scale (ESS), depression (Pichot scale), and the number of anxiety symptoms. Results: Participation in CBT was offered to 489 patients of whom 474 completed the programme and 154 were followed up at 3 months. Significant improvements in insomnia were seen: ISI score (17.74-14.27, P<0.0001) after CBT and at follow-up (13.78, P<0.0001). At the end of CBT, 76% (59/78) with initial severe insomnia and 52% (132/255) with moderate insomnia were improved, maintained at 3 months in 71% (15/21) …

Assessing depression symptoms in those with insomnia: an examination of the beck depression inventory second edition (BDI-II).
Background: Due to concerns about overlapping symptomatology between medical conditions and depression, the validity of the beck depression inventory (BDI-II) has been assessed in various medical populations. Although major depressive disorder (MDD) and primary insomnia (PI) share some daytime symptoms, the BDI-II has not been evaluated for use with insomnia patients. Method: Participants (N=140) were screened for the presence of insomnia using the Duke structured clinical interview for sleep disorders (DSISD), and evaluated for diagnosis of MDD using the structured clinical interview for DSM-IV-TR (SCID). Participants' mean BDI-II item responses were compared across two groups [insomnia with or without MDD) using multivariate analysis of variance (MANOVA), and the accuracy rates of suggested clinical cutoffs for the BDI-II were evaluated using a receiver operating characteristic (ROC) c…

Sleep onset insomnia symptoms during hospitalization for major burn injury predict chronic pain.
Both cross-sectional studies of chronic pain and sleep deprivation experiments suggest a bi-directional relationship between sleep and pain. Few longitudinal studies, however, have assessed whether acute insomnia following traumatic injury predicts the development of persistent pain. We sought to evaluate (1) whether in-hospital insomnia independently predicts long-term pain after burn injury and (2) whether in-hospital pain predicts future insomnia symptoms. We analyzed data on 333 subjects hospitalized for major burn injury (72.7% male; mean age=41.1+/-14.5years) who were participating in the multi-site, Burn Model System project. Subjects completed measures of health, function (SF-36), and psychological distress (Brief Symptom Inventory) while in hospital, at 6, 12, and 24months after discharge. Participants were categorized as either having or not having sleep onset insomnia at disch…

The effects of sleep inertia following EEG-monitored short and long naps on perceptual, cognitive, and physical performance in recreational athletes.
The purpose of this study was to examine the effects of sleep inertia following naps of two durations on cognitive performance (reaction time and decision making), physical performance (countermovement jump (CMJ) and handgrip strength (HG)), and perceptual responses (i.e. sleepiness, fatigue, and readiness to perform). In a randomized, counterbalanced, crossover design, 17 physically active participants (9 males, 8 females, age: 23 ± 2 y) completed three conditions: no-nap (NN), a 25-min nap opportunity (N25), and a 90-min nap opportunity (N90). Naps were conducted in a controlled laboratory setting using a sleep pod. Nighttime sleep prior to each session was tracked using a wrist-worn actigraph, and sleep during naps was assessed using a forehead mounted EEG device. Following each condition, participants completed four 30-min test batteries within the first two post-nap hours (T1: 0-30 …

Effect of napping on a bean bag chair on sleep stage, muscle activity, and heart rate variability.
Background: Although ample evidence has demonstrated that daytime napping is beneficial for health and cognitive performance, bedding for napping has not yet been scientifically investigated. Objectives: To explore the effect of a bean bag chair on daytime napping and physiological parameters related to sleep. Methods: Fourteen healthy participants were enrolled within the context of a randomized, single-blind, crossover study to evaluate the effects of a bean bag chair in comparison with those of a urethane chair manufactured to have a similar shape. Electroencephalogram, electromyogram, and heart rate variability were recorded and compared between wakefulness and napping. Results: Electroencephalogram analyses revealed no significant differences in sleep architecture or frequency components; however, a significant decrease was found in electromyogram recordings in the trapezius muscle,…

Napping facilitates word learning in early lexical development.
Little is known about the role that night-time sleep and daytime naps play in early cognitive development. Our aim was to investigate how napping affects word learning in 16-month-olds. Thirty-four typically developing infants were assigned randomly to nap and wake groups. After teaching two novel object-word pairs to infants, we tested their initial performance with an intermodal preferential looking task in which infants are expected to increase their target looking time compared to a distracter after hearing its auditory label. A second test session followed after approximately a 2-h delay. The delay contained sleep for the nap group or no sleep for the wake group. Looking behaviour was measured with an automatic eye-tracker. Vocabulary size was assessed using the Oxford Communicative Development Inventory. A significant interaction between group and session was found in preferential …

Memory improvement via slow-oscillatory stimulation during sleep in older adults.
We examined the intriguing but controversial idea that disrupted sleep-dependent consolidation contributes to age-related memory decline. Slow-wave activity during sleep may help strengthen neural connections and provide memories with long-term stability, in which case decreased slow-wave activity in older adults could contribute to their weaker memories. One prediction from this account is that age-related memory deficits should be reduced by artificially enhancing slow-wave activity. In young adults, applying transcranial current oscillating at a slow frequency (0.75 Hz) during sleep improves memory. Here, we tested whether this procedure can improve memory in older adults. In 2 sessions separated by 1 week, we applied either slow-oscillatory stimulation or sham stimulation during an afternoon nap in a double-blind, crossover design. Memory tests were administered before and after slee…
