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 To God belongs the Kingdom of the heavens and the earth, and to Him is the homecoming. 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 Allah Who alternates the Night and the Day: verily in these things is an instructive example for those who have vision! 44 God created every moving thing from water: One crawls on its belly, one walks on two legs, another moves on four. God creates whatsoever He will. Indeed God has power over everything. 45 We have sent down revelations clearly showing the truth. God guides whom He wills to the straight path. 46 They say: 'We believe in Allah and the Messenger and obey' But a party of them turn away after this. Those 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 are averters. 48 And if the truth be on their side, they come to him quickly, obedient. 49 Is there in their hearts a disease, or have they doubts, or fear they lest Allah and His messenger should wrong them in judgment? Nay, but such are evil-doers. 50
