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 To God belongs the kingdom of the heavens and the earth, and to God shall all things 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 God turns about the day and the night; surely in that is a lesson for those who have eyes. 44 And it is God who has created all animals out of water; and [He has willed that] among them are such as crawl on their bellies, and such as walk on two legs, and such as walk on four. God creates what He will: for, verily, God has the power to will anything. 45 We have sent down clarifying verses. Allah guides whom He will to a Straight Path. 46 They say, "We have believed in God and the Messenger and we have obeyed them." Then a group of them turn away from their (belief). They 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 are averters. 48 But if the right is theirs, they come to him in prompt obedience. 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
