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 'hast thou not seen how God drives the clouds, then composes them, then converts them into a mass, then thou seest the rain issuing out of the midst of them? And He sends down out of heaven mountains, wherein is hail, so that He smites whom He will with it, and turns it aside from whom He will; wellnigh the gleam of His lightning snatches away the sight. 43 Allah alternates the night and the day. Indeed in that is a lesson for those who have vision. 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 And We indeed sent down clear verses; and Allah may guide whomever He wills to the Straight Path. 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 When they are summoned to Allah and His messenger, in order that He may judge between them, behold some of them decline (to come). 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
