An-Naba 78:9–13

وَجَعَلْنَا نَوْمَكُمْ سُبَاتًا (and made your sleep a source of rest,...78:9). The word subat is derived from sabt which means to cut off. Sleep is something that cuts off the worries and tensions one may have, and thus gives him such a rest that cannot be attained from anything else. Therefore, some scholars translate the word subat as 'rest'.

Sleep Is a Great Gift

After mentioning in verse [ 8] that Allah has created mankind in pairs, Allah Ta’ ala states in verse [ 9] that among the means of their comfort, He created sleep, which is a great divine gift. Sleep is a great source of relaxation for the entire creation - for rich as well as for poor, for learned people, as well as for the illiterate ones, for kings as well as for labourers. This gift is made available equally and simultaneously for all. Rather, experience shows that this gift is most readily available to the poor and labouring class, as compared to the affluent and the elite class. The latter class has all the means of comfort, they have comfortable homes, they have moderately warm and cold places, they have comfortable mattresses and pillows that are rarely available to the poor. But the gift of sleep is not dependent upon the mattresses, pillows, cottages and bungalows. It is purely a divine gift that is given directly by Allah. Often the poor, with no means of comfort and without bed or bedding, enjoy the best sleep in an open space. Sometimes, the affluent and the men of means suffer from insomnia and can only get sleep when they take sleeping pills. Often the pills do not work either. Not only that this great gift is given to all creatures - humans as well as animals - and it is given free of charge, without working for it. Allah has made it compulsory for everyone in a way that even if he wishes to keep awake because of load of work, sleep is imposed on him by Allah's mercy, so that his tiredness is removed and he is refreshed to work further. This arrangement is a wonderful means of providing rest and peace for man.

وَجَعَلْنَا اللَّيْلَ لِبَاسًا (and made the night a covering... 78:10) This points to the fact that man naturally feels sleepy when light decreases and darkness prevails, when there is tranquility all around and there is absence of noises. The verse under comment additionally signifies that Allah did not only give man sleep, but created in the entire world conditions that are suitable for sleep. That is to say: [ 1] darkness of night; [ 2] the state of sleep is imposed on all humans and animals simultaneously, so that they sleep at the same time. In this way, there will be peace and tranquility throughout the world. Like other works, if there are different times for different people to sleep, no one will have peace and tranquility.

Thereafter the verse reads:

وَجَعَلْنَا النَّهَارَ‌ مَعَاشًا (and made the day a source of livelihood....78:11). Man requires, together with sleep, other essentials of life, such as livelihood. Otherwise, the sleep will turn into death. If the world would have had only nights and no days, and man would have continued to sleep all the time, how would he have obtained his livelihood and other essentials, whereas day is the time when he could work hard and make activities in the daylight in order to earn a living. Thus the verses under comment purport to say that Allah has, in order to complete the comforts of life, made the night a cloak and the day for earning a living. وَجَعَلْنَا سِرَ‌اجًا وَهَّاجًا .

Now attention is drawn to the comforts we get from the sky. The most useful thing in the sky is the light of the sun. It is mentioned in the following verse: وَجَعَلْنَا سِرَ‌اجًا وَهَّاجًا . (and created a luminous lamp [ the sun ]....78:13). Then, among the useful things below the sky, the most beneficial and the most essential thing is the raining clouds which are mentioned thus:
