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 And to Allah belongs the sovereignty of the heavens and the earth, and to Allah is the return (of all). 42 See you not that Allah drives the clouds gently, then joins them together, then makes them into a heap of layers, and you see the rain comes forth from between them. And He sends down from the sky hail (like) mountains, (or there are in the heaven mountains of hail from where He sends down hail), and strike therewith whom He will, and averts it from whom He wills. The vivid flash of its (clouds) lightning nearly blinds the sight. [Tafsir At-Tabari]. 43 He alternates the day and the night: there is indeed a lesson in it for those who have observing eyes. 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 believe in Allah and in the apostle and we obey; then a party of them turn back after this, and these are not believers. 47 And when they are called to Allah and His Apostle that he may judge between them, lo! a party of them turn aside. 48 but if the truth happens to be to their liking, they are quite willing to accept it! 49 Is there disease in their hearts? Or have they begun to doubt [that this is a divine writ]? Or do they fear that God and His Apostle might deal unjustly with them? Nay, it is [but] they, they who are doing wrong [to themselves]! 50
