﴿ هُوَ ٱلَّذِى جَعَلَ لَكُمُ ٱلَّيْلَ لِتَسْكُنُوا۟ فِيهِ وَٱلنَّهَارَ مُبْصِرًا ۚ إِنَّ فِى ذَٰلِكَ لَءَايَٰتٍۢ لِّقَوْمٍۢ يَسْمَعُونَ ﴾

“[whereas] it is He who has made the night for you, so that you might have rest therein, and the day, to make [you] see in this, behold, there are messages indeed for people who [are willing to] listen.”

He it is Who made for you the night, of the body, that you should rest therein, and the day, of the spirit that you should perceive thereby the realities of things and that by which you might be guided to Him. Surely in that are signs for a folk who are able to hear, the speech of God and thus understand its esoteric meanings and bounds and discover thereby His attributes and His names and thus witness Him as He is described and qualified by these.
