Do you not observe that all those who are in the heavens and the earth, and the birds with outspread wings, glorify Allah? Each one knows the mode of its prayer and glorification, and Allah has full knowledge of all they do. 41 And to Allah belongs the sovereignty of the heavens and the earth, and to Allah is the return (of all). 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 Allah has created every [living] creature from water. And of them are those that move on their bellies, and of them are those that walk on two legs, and of them are those that walk on four. Allah creates what He wills. Indeed, Allah is over all things competent. 45 We have sent down clarifying verses. Allah guides whom He will to a Straight Path. 46 For, [many are] they [who] say: "We believe in God and in the Apostle, and we pay heed!" - but then, some of them turn away after this [assertion]: and these are by no means [true] believers. 47 When they are called to God and His Messenger that he may judge between them, lo, a party of them are swerving aside; 48 If the right is theirs, they would have hastened to him obediently. 49 Is there a sickness in their hearts, or, are they in doubt? Do they fear that Allah and His Messenger will be unjust? No, but those they are the harmdoers. 50
