[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 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 Allah alternates the night and the day. Indeed in that is a lesson for those who have vision. 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 We have indeed sent down signs that make things manifest: and Allah guides whom He wills to a way that is straight. 46 They say, "We believe in God and in the Messenger, and we obey." But then, even after that a group of them will turn away. Those are surely not believers 47 And when they are called to Allah (i.e. His Words, the Quran) and His Messenger (SAW), to judge between them, lo! a party of them refuse (to come) and turn away. 48 And if the judgement is in their favour, they come towards it willingly. 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
