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 unto Allah belongeth the Sovereignty of the heavens and the earth, and unto Allah is the journeying. 42 Do you not see that God moves the clouds gently, brings them together, piles them up, and then you can see the rain coming from them. He sends down hailstones from the mountains in the sky. With them He strikes or protects from them whomever He wants. The lightening can almost take away the sight. 43 It is God who alternates night and day. There is surely a lesson in this for men of sight. 44 And it is God who has created all animals out of water; and [He has willed that] among them are such as crawl on their bellies, and such as walk on two legs, and such as walk on four. God creates what He will: for, verily, God has the power to will anything. 45 Assuredly We have sent down revelations illuminating: and Allah guideth whomsoever He listeth unto a path straight. 46 They say, "We believe in Allah and in the messenger, and we obey": but even after that, some of them turn away: they are not (really) 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 And if the truth be on their side, they come to him quickly, obedient. 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
