Creator of Day and Night

In the alternation of night and day, and in all that Allah has created in the heavens and the earth, are signs for those who are mindful.

10:6Lo! in the difference of day and night and all that Allah hath created in the heavens and the earth are portents, verily, for folk who ward off (evil).

17:12And We appoint the night and the day two portents. Then We make dark the portent of the night, and We make the portent of the day sight-giving, that ye may seek bounty from your Lord, and that ye may know the computation of the years, and the reckoning; and everything have We expounded with a clear expounding.
