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 And unto Allah belongeth the Sovereignty of the heavens and the earth, and unto Allah is the journeying. 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 Allah alternates the night and the day. Indeed in that is a lesson for those who have vision. 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 Now We have sent down signs making all clear; God guides whomsoever He will to a straight path. 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 and when they are called to God and His Messenger so that he may judge between them, some of them turn away. 48 However, if the truth be on their side, they come towards the Messenger in all obedience. 49 Is there in their hearts a disease, or have they doubts, or fear they lest Allah and His messenger should wrong them in judgment? Nay, but such are evil-doers. 50
