Have you not seen that all those who are in the heavens and the earth, and the birds on the wing, sing the praises of God. Each one knows its obligations and its duties, and God knows whatever they do. 41 To God belongs the kingdom of the heavens and the earth, and to Him do all things 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 Allah Who alternates the Night and the Day: verily in these things is an instructive example for those who have vision! 44 And Allah created every creature from a sort of water: of them some one crawls upon its belly: another walks on two legs and still another on four; Allah creates whatever He wills for He has power over everything 45 And We indeed sent down clear verses; and Allah may guide whomever He wills to the Straight Path. 46 They say, "We believe in Allah and in the messenger, and we obey": but even after that, some of them turn away: they are not (really) Believers. 47 When they are called to God and His Messenger so that they will judge among them, suddenly, some of them turn away. 48 If the right is theirs, they would have hastened to him obediently. 49 Is there in their hearts a disease, or have they doubts, or fear they lest Allah and His messenger should wrong them in judgment? Nay, but such are evil-doers. 50
