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 do all things return. 42 Hast thou not seen how Allah wafteth the clouds, then gathereth them, then maketh them layers, and thou seest the rain come forth from between them; He sendeth down from the heaven mountains wherein is hail, and smiteth therewith whom He will, and averteth it from whom He will. The flashing of His lightning all but snatcheth away the 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 creature from a sort of water: of them some one crawls upon its belly: another walks on two legs and still another on four; Allah creates whatever He wills for He has power 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 believe in God and the Messenger, and we obey.' Then after that a party of them turn away; those -- they are not 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 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
