[Prophet], do you not see that all those who are in the heavens and on earth praise God, as do the birds with wings outstretched? Each knows his own mode of prayer and glorification: God has full knowledge of all that 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 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 We have certainly sent down distinct verses. And Allah guides whom He wills to a straight path. 46 For, [many are] they [who] say: "We believe in God and in the Apostle, and we pay heed!" - but then, some of them turn away after this [assertion]: and these are by no means [true] believers. 47 And when called towards Allah and His Noble Messenger in order that the Noble Messenger may judge between them, thereupon a group among them turns away. 48 However, if the truth be on their side, they come towards the Messenger in all obedience. 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
