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 Art thou not aware that it is God who causes the clouds to move onward, then joins them together, then piles them up in masses, until thou can see rain come forth from their midst? And He it is who sends down from the skies, by degrees, mountainous masses [of clouds] charged with hail, striking therewith whomever He wills and averting it from whomever He wills, [the while] the flash of His lightning well-nigh deprives [men of their] sight! 43 It is God who alternates night and day. There is surely a lesson in this for men of sight. 44 And Allah has created from water every living creature: so of them is that which walks upon its belly, and of them is that which walks upon two feet, and of them is that which walks upon four; Allah creates what He pleases; surely Allah has power over all things. 45 We have revealed illustrious revelations. God guides to the right path whomever He wants. 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 Allah and His Apostle that he may judge between them, lo! a party of them turn aside. 48 But if right had been with them they would have come unto him willingly. 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
