ART THOU NOT aware that it is God whose limitless glory all [creatures] that are in the heavens and on earth extol, even the birds as they spread out their wings? Each [of them] knows indeed how to pray unto Him and to glorify Him; and 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 Allah causeth the revolution of the day and the night. Lo! herein is indeed a lesson for those who see. 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 Allah and in the messenger, and we obey": but even after that, some of them turn away: they are not (really) 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 And if the truth be on their side, they come to him quickly, obedient. 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
