Translation of the verse 47 from Surah Al-Furqan : Number of verses 77 - - page 364 - Part 19.
And it is He Who makes the night a covering for you, and the sleep (as) repose, and makes the day Nushur (i.e. getting up and going about here and there for daily work, etc. after one's sleep at night or like resurrection after one's death).
And it is He who has made the night for you as clothing and sleep [a means for] rest and has made the day a resurrection.
(25:47) And it is Allah Who has ordained the night as a garment *60 for you, and the sleep as a repose of death, and the day as the time of return to life. *61
*60) The night is a "garment" in the sense that it covers and hides things.
*61) This verse has three objects:
(1) It provides a proof of Tauhid,
(2) It furnishes a proof of the possibility of life-after-death from everyday human experience, and
(3) It bears the good news that the night of ignorance has come to an end and now the bright day of Knowledge and Guidance has dawned. It is therefore inevitable that those who were sleeping the sleep of ignorance, will sooner or later wake up, but those who have slept the sleep of death, will not wake up and will themselves be deprived of life, while the business of the day will go on thriving even without them.
