Hast thou not seen how that whatsoever is in the heavens and in the earth extols God, and the birds spreading their wings? Each -- He knows its prayer and its extolling; and God knows the things they do. 41 And unto Allah belongeth the Sovereignty of the heavens and the earth, and unto Allah is the journeying. 42 Have you not seen that God drives the clouds, then joins them together and puts them fold on fold. Then you see the rain fall through them; and He sends down hail from the sky where there are mountains of it, and strikes those with it whom He will, and wards it off from whomsoever He please. His lightning could snatch away their eyes. 43 It is God who causes night and day to alternate: in this [too,] behold, there is surely a lesson for all who have eyes to see! 44 And Allah has created every animal from water: of them there are some that creep on their bellies; some that walk on two legs; and some that walk on four. Allah creates what He wills for verily Allah has power over all things. 45 We have indeed sent down signs that make things manifest: and Allah guides whom He wills to a way that is straight. 46 They say, "We have believed in God and the Messenger and we have obeyed them." Then a group of them turn away from their (belief). They are not believers. 47 When they are summoned to Allah and His messenger, in order that He may judge between them, behold some of them decline (to come). 48 Had right been on their side they would have come to him submissively. 49 Are their hearts sick? Do they have doubts or are they afraid that God and His Messenger may do injustice to them? In fact, they, themselves, are unjust. 50
