See you not (O Muhammad SAW) that Allah, He it is Whom glorify whosoever is in the heavens and the earth, and the birds with wings out-spread (in their flight). Of each one He (Allah) knows indeed his Salat (prayer) and his glorification, [or everyone knows his Salat (prayer) and his glorification], and Allah is All-Aware of what they do. 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 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 Assuredly We have sent down revelations illuminating: and Allah guideth whomsoever He listeth unto a path straight. 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 [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 But if right had been with them they would have come unto him willingly. 49 Is there disease in their hearts? Or have they doubted? Or do they fear that Allah will be unjust to them, or His Messenger? Rather, it is they who are the wrongdoers. 50
