Husbands should take good care of their wives, with [the bounties] God has given to some more than others and with what they spend out of their own money. Righteous wives are devout and guard what God would have them guard in their husbands’ absence. If you fear high-handedness from your wives, remind them [of the teachings of God], then ignore them when you go to bed, then hit them.If they obey you, you have no right to act against them: God is most high and great

Expend in the path of God.... And do what is beautiful. Surely God loves the beautiful-doers. The rich remove money from their wallets, the poor remove the rich from their hearts, and the tawḤīd-voicers remove all creatures from their secret cores-to this He alludes with His words, “Say 'God,' then leave them” [6:91]. The rich let wealth go from their wallets for the sake of the reward of that world, the poor let the rich go from their hearts for the sake of the Lord's religion, and the recognizers let the creatures go for the sake of seeing the Glorified. The rich spend their possessions in alms tax and charity in order to escape from hell, the worshipers spend their souls in the duties of worship to reach paradise, and the recognizers spend their spirits and hearts in the realities of witnessing to reach union with the Real. And do what is beautiful. Surely God loves the beautiful-doer

(Those who spend their wealth for the cause of Allah�) [2:262]. Said al-Kalbi: �This verse was revealed about 'Uthman ibn 'Affan and 'Abd al-Rahman ibn 'Awf. As for 'Abd al-Rahman ibn 'Awf, he went and gave the Messenger of Allah, Allah bless him and give him peace, four thousand silver coins to distribute in charity. 'Abd al-Rahman ibn 'Awf said to him: 'I have eight thousand silver coins; I have kept four thousand for me and my family and I loan these four thousands to my Lord'. The Messenger of Allah, Allah bless him and give him peace, said to him: 'May Allah bless for you that which you have kept and that which you have given'. And as for 'Uthman, may Allah be well pleased with him, he said: 'Upon me is the equipment of anyone who has no equipment for the Battle of Tabuk'.

The men stand over the women through that with which God has preferred some of them over others and that which they expend of their wealth. He gave the men more than the women because the burden is all on them, for theirs is the perfec- tion of strength and the eminence of aspiration. They carry burdens in the measure of strength or in the measure of aspiration. “Resolutions are made in the measure of the folk of resoluteness.”

The parable of those who spend their wealth in the way of Allah, is that of a grain (of corn); it grows seven ears, and each ear has a hundred grains. Allah gives manifold increase to whom He wills. And Allah is All-Sufficient for His creatures' needs, All-Knower (261) Rewards of Spending in Allah's Cause This is a parable that Allah made of the multiplication of rewards for those who spend in His cause, seeking His pleasure. Allah multiplies the good deed ten to seven hundred times.

The roots of human altruism.: Human infants as young as 14 to 18 months of age help others attain their goals, for example, by helping them to fetch out-of-reach objects or opening cabinets for them. They do this irrespective of any reward from adults (indeed external rewards undermine the tendency), and very likely with no concern for such things as reciprocation and reputation, which serve to maintain altruism in older children and adults. Humans' nearest primate relatives, chimpanzees, also help others instrumentally with

Parochial altruism has distinct survival functions, and the brain may have evolved to sustain and promote in-group cohesion and effectiveness and to ward off threatening out-groups.

Evolution of prosocial behaviours in multilayer populations.

Human societies include diverse social relationships. Friends, family, business colleagues and online contacts can all contribute to one's social life. Individuals may behave differently in different domains, but success in one domain may engender success in another. Here, we study this problem using multilayer networks to model multiple domains of social interactions, in which individuals experience different environments and may express different behaviours. We provide a mathematical analysis and find that coupling between layers tends to promote prosocial behaviour. Even if prosociality is disfavoured in each layer alone, multilayer coupling can promote its proliferation in all layers simultaneously. We apply this analysis to six real-world multilayer networks, ranging from the socio-emotional and professional relationships in a Zambian community, to the online and offline relationshi

Student-teacher relationship quality and prosocial behaviour: The mediating role of academic achievement and a positive attitude towards school.

Background: The current research investigated the association between teacher-student relationship (both teacher-perceived and student-perceived relationship quality) and students' prosocial behaviours, as well as the mediating roles of students' attitudes towards school and perceived academic competence in this association. Sample: Four hundred and fifty-nine Italian primary students (aged 4-9, Mage  = 7.05, SDage  = 1.37) and 47 teachers (aged 26-60, Mage  = 48.35, SDage  = 8.13) participated and finished all the questionnaires and scales. Methods: Multiple regression analyses and bootstrapping analyses were employed to test the direct and the mediating effects between the teacher/student-perceived relationship and students' prosocial behaviours.

Adverse childhood experiences and trajectories of internalizing, externalizing, and prosocial behaviors from childhood to adolescence.

Background: Adverse childhood experiences (ACEs) predict poorer mental health across the life course but most of the extant research has employed ACE scores or individual adversities using retrospective data. Objectives: To study the impact of ACEs on later mental health using not only ACEs scores and individual ACEs, but also latent class analysis (LCA), which respects the clustering of adversities. Participants and setting: 8823 members from the UK Millennium Cohort Study. Methods: We investigated the impact of prospectively reported ACEs on mental health trajectories derived using the Strengths and Difficulties Questionnaire at age 3, 5, 7, 11 and 14. Associations between LCA-derived ACE clusters, ACE scores, individual ACEs and mental health trajectories were tested using linear mixed effects models.

This study aimed to examine longitudinal association between green space quality and prosocial behaviour among children. Methods: We analysed 10-year longitudinal data (2004-2014) from the Longitudinal Study of Australian Children (LSAC), a nationally representative cohort study. Prosocial behaviour that covers positive behaviours (e.g. sharing, helping) was measured using a prosocial scale from Goodman's Strengths and Difficulties Questionnaire (SDQ). Parents' perceptions on the availability of "good" parks, playgrounds, and play space in the neighbourhood assessed green space quality. Multilevel linear regression models were used to examine potential changes in pros

Feasibility and acceptability of a novel community-based mental health intervention delivered by community volunteers in Maharashtra, India: the Atmiyata programme.

Background: Many community-based intervention models for mental health and wellbeing have undergone robust experimental evaluation; however, there are limited accounts of the implementation of these evidence-based interventions in practice. Atmiyata piloted the implementation of a community-led intervention to identify and understand the challenges of delivering such an intervention. The goal of the pilot evaluation is to identify factors important for larger-scale implementation across an entire district in India. This paper presents the results of a feasibility and acceptability study of the Atmiyata intervention piloted in Nashik district, Maharashtra, India between 2013 and 2015. Methods: A mixed methods approach was used to evaluate the Atmiyata intervention. First, a pre-post survey conducted with 215 cases identified with a GHQ cut-off 6 using a 3-month interval. Cases enrolled in

A daily diary study on adolescents' mood, empathy, and prosocial behavior during the COVID-19 pandemic.

Adolescence is a formative phase for social development. The COVID-19 pandemic and associated regulations have led to many changes in adolescents' lives, including limited opportunities for social interactions. The current exploratory study investigated the effect of the first weeks of COVID-19 pandemic lockdown on Dutch adolescents' (N = 53 with attrition, N = 36 without attrition) mood, empathy, and prosocial behavior. Longitudinal analyses comparing pre-pandemic measures to a three-week peri-pandemic daily diary study showed (i) decreases in empathic concern, opportunities for prosocial actions, and tension, (ii) stable levels of social value orientation, altruism, and dire prosociality, and (iii) increased levels of perspective-taking and vigor during the first weeks of lockdown. Second, this study investigated peri-pandemic effects of familiarity, need, and deservedness on giving be

Oxytocin in the anterior cingulate cortex is involved in helping behaviour.

Empathy toward the distress of others is thought to motivate helping behaviour, in the form of voluntary action to eliminate that distress. Neuropeptide oxytocin is associated with various social cognitive abilities, including empathy and prosocial behaviour. The anterior cingulate cortex is known to be one of the brain regions underlying empathy, and one in which oxytocin receptors are expressed. However, the relationship between helping behaviour and oxytocin in the anterior cingulate cortex is still unclear. The present study investigated whether oxytocin in the anterior cingulate cortex is involved in rats' helping behaviour. In Experiment 1, we examined the influence of blockading the oxytocin receptors in the anterior cingulate cortex on helping behaviour. Impeding oxytocin in the anterior cingulate cortex delayed learning of the helping behaviour. In Experiment 2, we examined immu

Childhood maltreatment and prosocial behavior among Chinese adolescents: Roles of empathy and gratitude.

Background: Childhood maltreatment, including both abuse (physical, emotional, and sexual) and neglect (physical and emotional), is especially detrimental to adolescent development. However, most studies have been conducted within a psychopathological framework and focused on its role in exacerbating negative outcomes. Its adverse effect on adolescents' positive functioning, including empathy, gratitude, and prosocial behavior, is relatively underexplored. Objective: Guided by attachment theory, empathy-altruism hypothesis, and broaden-and-build theory of positive emotions, this study examined the relationship between childhood maltreatment and prosocial behavior using a multiple mediation model that included empathy and gratitude as hypothesized mediators. Methods: A sample of 897 adolescent students (45.80 % males and 54.20 % females; Mage = 15.41 years, SD = 1.73) completed questionna

Helping-Like Behaviour in Mice Towards Conspecifics Constrained Inside Tubes.

Prosocial behaviour, including helping behaviour, benefits others. Recently, helping-like behaviour has been observed in rats, but whether it is oriented towards rescue, social contact with others, or other goals remains unclear. Therefore, we investigated whether helping-like behaviour could be observed in mice similar to that in rats. Because mice are social animals widely used in neuroscience, the discovery of helping-like behaviour in mice would be valuable in clarifying the psychological and biological mechanisms underlying pro-sociability. We constrained mice inside tubes. Subject mice were allowed to move freely in cages with tubes containing constrained conspecifics. The subject mice released both cagemates and stranger mice but did not engage in opening empty tubes. Furthermore, the same behaviour was observed under aversive conditions and with anesthetised conspecifics. Interes

Real-life helping behaviours in North America: A genome-wide association approach.

In humans, prosocial behaviour is essential for social functioning. Twin studies suggest this distinct human trait to be partly hardwired. In the last decade research on the genetics of prosocial behaviour focused on neurotransmitters and neuropeptides, such as oxytocin, dopamine, and their respective pathways. Recent trends towards large scale medical studies targeting the genetic basis of complex diseases such as Alzheimer's disease and schizophrenia pave the way for new directions also in behavioural genetics. Based on data from 10,713 participants of the American Health and Retirement Study we estimated heritability of helping behaviour-its total variance explained by 1.2 million single nucleotide polymorphisms-to be 11%. Both, fixed models and mixed linear models identified rs11697300, an intergene variant on chromosome 20, as a candidate variant moderating this particular helping b

Mesotocin influences pinyon jay prosociality.

Many species exhibit prosocial behaviour, in which one individual's actions benefit another individual, often without an immediate benefit to itself. The neuropeptide oxytocin is an important hormonal mechanism influencing prosociality in mammals, but it is unclear whether the avian homologue mesotocin plays a similar functional role in birds. Here, we experimentally tested prosociality in pinyon jays (Gymnorhinus cyanocephalus), a highly social corvid species that spontaneously shares food with others. First, we measured prosocial preferences in a prosocial choice task with two different pay-off distributions: Prosocial trials delivered food to both the subject and either an empty cage or a partner bird, whereas Altruism trials delivered food only to an empty cage or a partner bird (none to subject). In a second experiment, we examined whether administering mesotocin influenced prosocia

Helping the One You Hurt: Toddlers' Rudimentary Guilt, Shame, and Prosocial Behavior After Harming Another.

This study explored the role of guilt and shame in early prosocial behavior by extending previous findings that guilt- and shame-like responses can be distinguished in toddlers and, for the first time, examining their associations with helping. Toddlers (n = 32; Mage  = 28.9 months) were led to believe they broke an adult's toy, after which they exhibited either a guilt-like response that included frequently confessing their behavior and trying to repair the toy; or a shame-like response that included frequently avoiding the adult and seldom confessing or attempting to repair the toy. In subsequent prosocial tasks, children showing a guilt-like response helped an adult in emotional distress significantly faster and more frequently than did children showing a shame-like response.

The nature of prosociality in chimpanzees.

An important debate centres around the nature of prosociality in nonhuman primates. Chimpanzees help other individuals in some experimental settings, yet they do not readily share food. One solution to this paradox is that they are motivated to help others provided there are no competing interests. However, benefits to recipients could arise as by-products of testing. Here we report two studies that separate by-product from intended helping in chimpanzees using a GO/NO-GO paradigm. Actors in one group could help a recipient by releasing a food box, but the same action for another group prevented a recipient from being able to get food. We find no evidence for helping-chimpanzees engaged in the test regardless of the effects on their partners. Illusory prosocial behaviour could arise as a by-product of task design.

Helping from the heart: Voluntary upregulation of heart rate variability predicts altruistic behavior.

Our various daily activities continually require regulation of our internal state. These regulatory processes covary with changes in High Frequency Heart Rate Variability (HF-HRV), a marker of parasympathetic activity. Specifically, incidental increases in HF-HRV accompany positive social engagement behavior and prosocial action. Little is known about deliberate regulation of HF-HRV and the role of voluntary parasympathetic regulation in prosocial behavior. Here, we present a novel biofeedback task that measures the ability to deliberately increase HF-HRV. In two large samples, we find that a) participants are able to voluntarily upregulate HF-HRV, and b) variation in this ability predicts individual differences in altruistic prosocial behavior, but not non-altruistic forms of prosociality, assessed through 14 different measures. Our findings suggest that self-induction of parasympatheti

Increased social anhedonia and reduced helping behaviour in young people with high depressive symptomatology.

Background: Social anhedonia, the decreased enjoyment of pleasant social experiences, is associated with depression. However, whether social anhedonia in depression affects prosocial behaviours is unclear. The current study aimed to examine how high levels of depressive symptomatology in young people affect responses to usually rewarding social situations, including helping behaviour. Methods: We recruited 46 females, 16 scoring high on the Beck Depression Inventory (BDI scores>20, Mage=19; HD) and 30 scoring low (BDI<10, Mage=20; LD). In a social emotion task (SET), participants were presented with social scenarios and asked to rate their expected emotional responses. Subsequently, participants' helping behaviour was measured by dropping a pile of papers near them and recording their responses. Lastly, participants completed the SET again. Results: The SET at time 1 revealed that HD ind

Increasing opportunities for the productive engagement of older adults: a response to population aging.

"Productive aging" puts forward the fundamental view that the capacity of older adults must be better developed and utilized in activities that make economic contributions to society-working, caregiving, volunteering. It is suggested that productive engagement can lead to multiple positive ends: offsetting fiscal strains of a larger older population, contributing to the betterment of families and civil society, and maintaining the health and economic security of older adults. Advocates claim that outdated social structures and discriminatory behaviors limit participation of older adults in these important social roles as well as prevent the optimization of outcomes for older adults, families, and society. We ask two important questions: (a) How can we shape policies and programs to optimally engage the growing resources of an aging population for the sake of society and older adults them

Four-year-olds' strategic allocation of resources: attempts to elicit reciprocation correlate negatively with spontaneous helping.

Behaviour benefitting others (prosocial behaviour) can be motivated by self-interested strategic concerns as well as by genuine concern for others. Even in very young children such behaviour can be motivated by concern for others, but whether it can be strategically motivated by self-interest is currently less clear. Here, children had to distribute resources in a game in which a rich but not a poor recipient could reciprocate. From four years of age participants strategically favoured the rich recipient, but only when recipients had stated an intention to reciprocate. Six- and eight-year-olds distributed more equally. Children allocating strategically to the rich recipient were less likely to help when an adult needed assistance but was not in a position to immediately reciprocate, demonstrating consistent cross-task individual differences in the extent to which social behaviour is self

Empathic concern drives costly altruism.

Why do we self-sacrifice to help others in distress? Two competing theories have emerged, one suggesting that prosocial behavior is primarily motivated by feelings of empathic other-oriented concern, the other that we help mainly because we are egoistically focused on reducing our own discomfort. Here we explore the relationship between costly altruism and these two sub-processes of empathy, specifically drawing on the caregiving model to test the theory that trait empathic concern (e.g. general tendency to have sympathy for another) and trait personal distress (e.g. predisposition to experiencing aversive arousal states) may differentially drive altruistic behavior. We find that trait empathic concern--and not trait personal distress--motivates costly altruism, and this relationship is supported by activity in the ventral tegmental area, caudate and subgenual anterior cingulate, key reg

Neural and cognitive characteristics of extraordinary altruists.

Altruistic behavior improves the welfare of another individual while reducing the altruist's welfare. Humans' tendency to engage in altruistic behaviors is unevenly distributed across the population, and individual variation in altruistic tendencies may be genetically mediated. Although neural endophenotypes of heightened or extreme antisocial behavior tendencies have been identified in, for example, studies of psychopaths, little is known about the neural mechanisms that support heightened or extreme prosocial or altruistic tendencies. In this study, we used structural and functional magnetic resonance imaging to assess a population of extraordinary altruists: altruistic kidney donors who volunteered to donate a kidney to a stranger. Such donations meet the most stringent definitions of altruism in that they represent an intentional behavior that incurs significant costs to the donor to

Participation in productive activities and health outcomes among older adults in urban China.

Purpose of the study: This study examined whether participating in productive activities was associated with better health outcomes among older adults in urban China, including analysis of potential gender differences. Design and methods: Using a sample of 10,016 urban Chinese adults aged 60 years or older from the 2006 Sample Survey of the Aged Population in Urban/Rural China, we regressed measures of self-rated health, functional health, and depression on productive activities (paid employment, helping with family, and volunteering), controlling for sociodemographic variables. Results: Those who provided assistance to family members or volunteered had significantly lower levels of depression and better functional and self-rated health than their counterparts. Older adults with paid job, providing family assistance, or volunteering reported significantly lower levels of depression and b

Selfish or selfless? On the signal value of emotion in altruistic behavior.

Theories that reject the existence of altruism presume that emotional benefits serve as ulterior motives for doing good deeds. These theories argue that even in the absence of material and reputational benefits, individuals reap utility from the feelings associated with doing good. In response to this normative view of altruism, this article examines the descriptive question of whether laypeople penalize emotional prosocial actors. Six studies find that emotion serves as a positive signal of moral character, despite the intrapsychic benefits associated with it. This is true when emotion motivates prosocial behavior (Studies 1, 2, 3, and 5) and when emotion is a positive outcome of prosocial behavior (i.e., "warm glow"; Studies 4, 5, and 6). Emotional actors are considered to be moral because people believe emotion provides an honest and direct signal that the actor feels a genuine concer

Fourteen-month-old infants use interpersonal synchrony as a cue to direct helpfulness.

Musical behaviours such as dancing, singing and music production, which require the ability to entrain to a rhythmic beat, encourage high levels of interpersonal coordination. Such coordination has been associated with increased group cohesion and social bonding between group members. Previously, we demonstrated that this association influences even the social behaviour of 14-month-old infants. Infants were significantly more likely to display helpfulness towards an adult experimenter following synchronous bouncing compared with asynchronous bouncing to music. The present experiment was designed to determine whether interpersonal synchrony acts as a cue for 14-month-olds to direct their prosocial behaviours to specific individuals with whom they have experienced synchronous movement, or whether it acts as a social prime, increasing prosocial behaviour in general.

Participation in productive activities and depression among older Europeans: survey of Health, Ageing and Retirement in Europe (SHARE).

Objective: Although engagement in productive activities is associated with favourable outcomes with respect to the health and well-being of older individuals, the association between such activities and depression in older populations remains relatively unexplored. The purpose of this study was to evaluate the association among five productive activities (paid work, formal volunteering, caregiving, informal helping and caring for grandchildren) with depression in older adults in 14 European countries. Methods: This cross-sectional study used the first two waves of data collected by the Survey of Health, Ageing and Retirement in Europe and analysed a total sample of 7238 relatively healthy community residents aged 60 years and older from 14 European countries.

The legacy of altruism in health care: the promotion of empathy, prosociality and humanism.

Objectives: This study aimed to examine concepts of altruism and empathy among medical students and professionals in conjunction with health care initiatives designed to support the maintenance of these qualities. Methods: We searched for the terms 'altruism', 'altruistic', 'helping', 'prosocial behaviour' and 'empathy' in the English-language literature published from 1980 to the present within the Ovid MEDLINE, PsycInfo and PubMed databases. We used conceptual analysis to examine the relationships among altruism, empathy and related prosocial concepts in health care in order to understand how such factors may relate to emotional and career burnout, cynicism, decreased helping and decreased patient-centredness in care. Results: Altruistic ideals and qualities of empathy appear to decrease among some medical students as they progress through their education. During this process, students

Recipients affect prosocial and altruistic choices in jackdaws, Corvus monedula.

Other-regarding preferences are a critical feature of human cooperation but to what extent non-human animals exhibit these preferences is a matter of intense discussion. We tested whether jackdaws show prosocial behaviour (providing benefits to others at no cost to themselves) and altruism (providing benefits to others while incurring costs) with both sibling and non-sibling recipients. In the prosocial condition, a box was baited on both the actor's and the recipient's side (1/1 option), whereas another box provided food only for the actor (1/0 option). In the altruistic condition, the boxes contained food for either the actor (1/0 option) or the recipient (0/1 option). The proportion of selfish (1/0 option) and cooperative (1/1 and 0/1 option, respectively) actors' choices was significantly affected by the recipients' behaviour. If recipients approached the boxes first and positioned t
