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 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 It is Allah Who alternates the Night and the Day: verily in these things is an instructive example for those who have vision! 44 God created every moving thing from water: One crawls on its belly, one walks on two legs, another moves on four. God creates whatsoever He will. Indeed God has power over everything. 45 Certainly We have revealed clear communications, and Allah guides whom He pleases to the right way. 46 They say: 'We believe in Allah and the Messenger and obey' But a party of them turn away after this. Those are not believers. 47 And when they are called to Allah and His Messenger so that he judges between them, a party of them swerve away. 48 If right was on their side, they would come quickly. 49 Is there a malady in their hearts, or they are deluded, or afraid that God and His Prophet would be unjust in dealing with them? Not so; they are themselves unjust. 50
