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 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 Allah alternates the night and the day. Indeed in that is a lesson for those who have vision. 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 Certainly We have revealed clear communications, and Allah guides whom He pleases to the right way. 46 And they say: We believe in Allah and in the apostle and we obey; then a party of them turn back after this, and these are not believers. 47 And when they are called to Allah and His apostle that he may judge between them, lo! a party of them are averters. 48 But if right had been with them they would have come unto him 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
