Hast thou not seen that Allah, He it is Whom all who are in the heavens and the earth praise, and the birds in their flight? Of each He knoweth verily the worship and the praise; and Allah is Aware of what 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 It is God who alternates night and day. There is surely a lesson in this for men of sight. 44 Allah hath created every animal of water. Of them is (a kind) that goeth upon its belly and (a kind) that goeth upon two legs and (a kind) that goeth upon four. Allah createth what He will. Lo! Allah is Able to do all things. 45 We have sent down Revelations that make the reality quite plain; however, Allah guides to the straight path whomsoever He pleases. 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 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 And if the judgement is in their favour, they come towards it willingly. 49 Is in their hearts a disease? or doubt they? or fear they that Allah shall misjudge them, as also His apostle? Aye! these are the very wrong-doers! 50
