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 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 Allah causeth the revolution of the day and the night. Lo! herein is indeed a lesson for those who see. 44 God has created every beast of water, and some of them go upon their bellies, and some of them go upon two feet, and some of them go upon four; God creates whatever He will; God is powerful over everything. 45 We have surely sent down clear signs. It is God who guides whom He will to the path that is straight. 46 They say, "We have believed in God and the Messenger and we have obeyed them." Then a group of them turn away from their (belief). They are not believers. 47 When they are called to God and His Messenger so that they will judge among them, suddenly, some of them turn away. 48 but if the truth happens to be to their liking, they are quite willing to accept it! 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
