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 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 It is God who alternates night and day. There is surely a lesson in this for men of sight. 44 Allah created everything that walks from water. Some creep upon their bellies, others walk on two feet, and others walk on four. Allah creates whatever He will. Allah is Powerful over everything. 45 We have sent down Revelations that make the reality quite plain; however, Allah guides to the straight path whomsoever He pleases. 46 For, [many are] they [who] say: "We believe in God and in the Apostle, and we pay heed!" - but then, some of them turn away after this [assertion]: and these are by no means [true] believers. 47 And when they are called to Allah (i.e. His Words, the Quran) and His Messenger (SAW), to judge between them, lo! a party of them refuse (to come) and turn away. 48 However, if the truth be on their side, they come towards the Messenger in all obedience. 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
