Do you not see that Allah is exalted by whomever is within the heavens and the earth and [by] the birds with wings spread [in flight]? Each [of them] has known his [means of] prayer and exalting [Him], and Allah is Knowing 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 Allah turns over the night and the day; most surely there is a lesson in this for those who have sight. 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 sent down clarifying verses. Allah guides whom He will to a Straight Path. 46 And they say: we have believed in Allah and in the apostle and we have obeyed; then there backslide a party of them thereafter: and these are not believers. 47 And when they are called to [the words of] Allah and His Messenger to judge between them, at once a party of them turns aside [in refusal]. 48 But if the truth happens to be to their liking, they are quite willing to accept it! 49 Is there a sickness in their hearts, or, are they in doubt? Do they fear that Allah and His Messenger will be unjust? No, but those they are the harmdoers. 50
