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 To God belongs the kingdom of the heavens and the earth, and to Him do all things return. 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 God alternates the night and the day -- truly, in this there is a lesson for men of insight. 44 Allah hath created every moving creature of water; of them is one that walketh upon his belly; and of them is one that walketh upon its two feet; and of them is one that walketh upon four. Allah createth whatsoever He listeth; verily Allah is over everything Potent. 45 And We indeed sent down clear verses; and Allah may guide whomever He wills to the Straight Path. 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 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 Are their hearts afflicted with the disease (of hypocrisy)? Or, are they in doubt? Or, do they fear that Allah and His Messenger will be unjust to them? In fact, they themselves are unjust. 50
