Seest thou not that it is Allah Whose praises all beings in the heavens and on earth do celebrate, and the birds (of the air) with wings outspread? Each one knows its own (mode of) prayer and praise. And Allah knows well all that they do. 41 And to Allah belongs the dominion of the heavens and the earth, and to Allah is the destination. 42 Do you not see that Allah drives along the clouds, then gathers them together, then piles them up, so that you see the rain coming forth from their midst? And He sends down of the clouds that are (like) mountains wherein is hail, afflicting therewith whom He pleases and turning it away from whom He pleases; the flash of His lightning almost takes away the sight. 43 It is Allah Who alternates the Night and the Day: verily in these things is an instructive example for those who have vision! 44 And Allah created every creature from a sort of water: of them some one crawls upon its belly: another walks on two legs and still another on four; Allah creates whatever He wills for He has power over everything 45 And We indeed sent down clear verses; and Allah may guide whomever He wills to the Straight Path. 46 And they say: We believe in Allah and in the apostle and we obey; then a party of them turn back after this, and these are not believers. 47 and when they are called to God and His Messenger so that he may judge between them, some of them turn away. 48 but if they are in the right, they will 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
