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 It is God who causes night and day to alternate: in this [too,] behold, there is surely a lesson for all who have eyes to see! 44 And Allah created every animal on earth, from water; so among them is a kind that moves upon its belly; and among them is a kind that moves upon two legs; and among them a kind that moves upon four legs; Allah creates whatever He wills; indeed Allah is Able to do all things. 45 We have surely sent down clear signs. It is God who guides whom He will to the path that is straight. 46 And they say: We believe in Allah and the messenger, and we obey; then after that a faction of them turn away. Such are not believers. 47 When they are called to God and His Prophet, that he may judge between them, a section of them turns away. 48 However, if the truth be on their side, they come towards the Messenger in all obedience. 49 Is there disease in their hearts? Or have they begun to doubt [that this is a divine writ]? Or do they fear that God and His Apostle might deal unjustly with them? Nay, it is [but] they, they who are doing wrong [to themselves]! 50
