Seest thou not that it is Allah Whose praises all beings in the heavens and on earth do celebrate, and the birds (of the air) with wings outspread? Each one knows its own (mode of) prayer and praise. And Allah knows well all that they do. 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 alternates night and day. There is surely a lesson in this for men of sight. 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 We have certainly sent down distinct verses. And Allah guides whom He wills to a straight path. 46 They say: 'We believe in Allah and the Messenger and obey' But a party of them turn away after this. Those 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 And if the truth be on their side, they come to him quickly, obedient. 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
