Beholdest thou not that Allah - those hallow Him whosoever is in the heavens and the earth and the birds with wings outspread? Surely each one knoweth his prayer and his hallowing; and Allah is the Knower of that which they do. 41 And for Allah only is the kingship of the heavens and the earth; and towards 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 God alternates the night and the day. In this there is a lesson for the people of understanding. 44 And it is God who has created all animals out of water; and [He has willed that] among them are such as crawl on their bellies, and such as walk on two legs, and such as walk on four. God creates what He will: for, verily, God has the power to will anything. 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 When they are called to God and His Messenger that he may judge between them, lo, a party of them are swerving aside; 48 If the right is theirs, they would have hastened to him obediently. 49 What, is there sickness in their hearts, or are they in doubt, or do they fear that God may be unjust towards them and His Messenger? Nay, but those -- they are the evildoers. 50
