Have you not seen that all those who are in the heavens and the earth praise Allah, and the birds with their wings spread (also praise Him)? Each one has learnt its prayers and its words of praise; and Allah knows their deeds. 41 And to Allah belongs the sovereignty of the heavens and the earth, and to Allah is the return (of all). 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 Allah hath created every animal of water. Of them is (a kind) that goeth upon its belly and (a kind) that goeth upon two legs and (a kind) that goeth upon four. Allah createth what He will. Lo! Allah is Able to do all things. 45 Verily We have sent down revelations and explained them. Allah guideth whom He will unto a straight path. 46 And they say: we have believed in Allah and in the apostle and we have obeyed; then there backslide a party of them thereafter: and these are not believers. 47 And when called towards Allah and His Noble Messenger in order that the Noble Messenger may judge between them, thereupon a group among them turns away. 48 but if the truth happens to be to their liking, they are quite willing to accept it! 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
