Hast thou not seen how that whatsoever is in the heavens and in the earth extols God, and the birds spreading their wings? Each -- He knows its prayer and its extolling; and God knows the things 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 God alternates the night and the day. In this there is a lesson for the people of understanding. 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 indeed sent down signs that make things manifest: and Allah guides whom He wills to a way that is straight. 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 [so it is that] whenever they are summoned unto God and His Apostle in order that [the divine writ] might judge between them, lo! some of them turn away; 48 But if the right is with them, they come to him willingly with submission. 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
