وَجَعَلْنَا نَوْمَكُمْ سُبَاتًا (9)
(78:9) and made your sleep a means of repose, *7
*7) The explanation of the wisdom for which Allah Almighty has placed a desire for sleep in man's nature in order to make him fit for work in the world, and which impels him to a few hours' sleep after every few hours of work, has been given in E.N. 33 of Surah Ar-Rum.
