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 God who causes night and day to alternate: in this [too,] behold, there is surely a lesson for all who have eyes to see! 44 And Allah has created from water every living creature: so of them is that which walks upon its belly, and of them is that which walks upon two feet, and of them is that which walks upon four; Allah creates what He pleases; surely Allah has power over all things. 45 We have sent down clarifying verses. Allah guides whom He will to a Straight Path. 46 They say they believe in God and the Prophet, and have come to believe, yet a section of them turns back even after this; and these are not believers. 47 When they are called to Allah and His Messenger so that the Messenger may judge between them, a party of them turns away. 48 but if they are in the right, they will come to him submissively. 49 Is there a sickness in their hearts, or, are they in doubt? Do they fear that Allah and His Messenger will be unjust? No, but those they are the harmdoers. 50
