Have you not seen that all those who are in the heavens and the earth, and the birds on the wing, sing the praises of God. Each one knows its obligations and its duties, and God knows whatever 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 God alternates the night and the day -- truly, in this there is a lesson for men of insight. 44 And Allah created every animal on earth, from water; so among them is a kind that moves upon its belly; and among them is a kind that moves upon two legs; and among them a kind that moves upon four legs; Allah creates whatever He wills; indeed Allah is Able to do all things. 45 Assuredly We have sent down revelations illuminating: and Allah guideth whomsoever He listeth unto a path straight. 46 They say they believe in God and the Prophet, and have come to believe, yet a section of them turns back even after this; and these 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 And if the truth be on their side, they come to him quickly, obedient. 49 Is in their hearts a disease? or doubt they? or fear they that Allah shall misjudge them, as also His apostle? Aye! these are the very wrong-doers! 50
