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 Allah's is the dominion of the heavens and the earth, and unto Allah is the 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 It is God who alternates night and day. There is surely a lesson in this for men of sight. 44 God has created every beast of water, and some of them go upon their bellies, and some of them go upon two feet, and some of them go upon four; God creates whatever He will; God is powerful over everything. 45 Certainly We have revealed clear communications, and Allah guides whom He pleases to the right way. 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 [so it is that] whenever they are summoned unto God and His Apostle in order that [the divine writ] might judge between them, lo! some of them turn away; 48 If the right is theirs, they would have hastened to him obediently. 49 Is it that there is a disease in their hearts? or do they doubt, or are they in fear, that Allah and His Messenger will deal unjustly with them? Nay, it is they themselves who do wrong. 50
