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 Allah turneth the night and the day over and over; verily therein is a lesson for men of insight. 44 And it is God who has created all animals out of water; and [He has willed that] among them are such as crawl on their bellies, and such as walk on two legs, and such as walk on four. God creates what He will: for, verily, God has the power to will anything. 45 We have indeed sent down signs that make things manifest: and Allah guides whom He wills to a way that is straight. 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 And when called towards Allah and His Noble Messenger in order that the Noble Messenger may judge between them, thereupon a group among them turns away. 48 And if the judgement is in their favour, they come towards it willingly. 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
