(72)It is out of His mercy that He has made for you the night and the day that you may rest therein and that you may seek of His bounty – and in order that you may be grateful (73)
Night and Day are among the Blessings of Allah and are Signs of Tawhid
Allah reminds His servants of His favors towards them by subjugating for them the night and day, without which they could not survive. He explains that if He made the night continuous, lasting until the Day of Resurrection, that would be harmful for them and would cause boredom and stress. So He says:

It was narrated from Zaid bin Thabit that :The Prophet (ﷺ) used some palm fiber mats to section off a small area in the masjid. And the Messenger of Allah (ﷺ) prayed in it for several nights until the people gathered around him. Then, one night they did not hear his voice, and they thought that he was sleeping, so they cleared their throats to make him come out to them. He said: 'You kept doing that until I feared that it would be made obligatory for you, and if it were made obligatory, you would not be able to do it. O people, pray in your houses, for the best prayer a person offers is in his house, apart from the prescribed (obligatory) prayers

Here, we tested the effect of a brief nap opportunity (30- or 60-min) during a period of sleep deprivation on two cognitive processes with broad scope, placekeeping and vigilant attention. In the evening, participants (N = 280) completed a placekeeping task (UNRAVEL) and a vigilant attention task (Psych

The authors tested the effect of a short, mid-day nap on the cognitive functioning and alertness of first-year internal medicine (IM) residents during normal duty hours.
Method: This was a controlled, interventional study performed between July 2008 and April 2010. The authors recruited a nap group of 18 residents and a rest (control) group of 11 residents. Investigators connected all participants to an ambul

The neurovisceral integration model suggests that resting vagally mediated heart rate variability (vmHRV) is linked with cognitive function. This study investigated the relationship between resting vmHRV and cognitive function after different nap durations in interns after shift work.
