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 dominion of the heavens and the earth, and to Allah is the destination. 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 Allah turneth the night and the day over and over; verily therein is a lesson for men of insight. 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 They say they believe in God and the Prophet, and have come to believe, yet a section of them turns back even after this; and these are not believers. 47 When they are called to Allah and His Messenger so that the Messenger may judge between them, a party of them turns away. 48 However, if the truth be on their side, they come towards the Messenger in all obedience. 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
