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 The kingdom of the heavens and the earth belongs to Allah alone, and all shall have to return to Him. 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 turns about the night and the day (to succeed one another); surely, in this there is a lesson for those who have eyes. 44 And Allah created every animal on earth, from water; so among them is a kind that moves upon its belly; and among them is a kind that moves upon two legs; and among them a kind that moves upon four legs; Allah creates whatever He wills; indeed Allah is Able to do all things. 45 Now We have sent down signs making all clear; God guides whomsoever He will to a straight path. 46 They say, 'We believe in God and the Messenger, and we obey.' Then after that a party of them turn away; those -- they 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 And if right had been theirs, they would have come to him readily. 49 Is there disease in their hearts? Or have they doubted? Or do they fear that Allah will be unjust to them, or His Messenger? Rather, it is they who are the wrongdoers. 50
