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 For God's is the kingdom of the heavens and the earth, and the returning is to God. 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 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 And We indeed sent down clear verses; and Allah may guide whomever He wills to the Straight Path. 46 They (hypocrites) say: "We have believed in Allah and in the Messenger (Muhammad SAW), and we obey," then a party of them turn away thereafter, such are not believers. 47 And when they appeal unto Allah and His messenger to judge between them, lo! a faction of them are averse; 48 but if the truth happens to be to their liking, they are quite willing to accept it! 49 Are their hearts sick? Do they have doubts or are they afraid that God and His Messenger may do injustice to them? In fact, they, themselves, are unjust. 50
