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 It is God who alternates night and day. There is surely a lesson in this for men of sight. 44 Allah has created every [living] creature from water. And of them are those that move on their bellies, and of them are those that walk on two legs, and of them are those that walk on four. Allah creates what He wills. Indeed, Allah is over all things competent. 45 We have sent down Revelations that make the reality quite plain; however, Allah guides to the straight path whomsoever He pleases. 46 These people say "We have believed in Allah and the Messenger and we have submitted"; but soon after this, some of them turn away (from obedience): such people are not true Believers. 47 When they are summoned to Allah and His messenger, in order that He may judge between them, behold some of them decline (to come). 48 If right was on their side, they would come quickly. 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
