Indeed, in the creation of the heavens and the earth and the alternation of the night and the day are signs for those of understanding –

Who remember Allah while standing or sitting or [lying] on their sides and give thought to the creation of the heavens and the earth, [saying], "Our Lord, You did not create this aimlessly; exalted are You [above such a thing]; then protect us from the punishment of the Fire.

Quran (3-90:191)
