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 for, God's is the dominion over the heavens and the earth, and with God is all journeys' end. 42 Seest thou not that Allah makes the clouds move gently, then joins them together, then makes them into a heap? - then wilt thou see rain issue forth from their midst. And He sends down from the sky mountain masses (of clouds) wherein is hail: He strikes therewith whom He pleases and He turns it away from whom He pleases, the vivid flash of His lightning well-nigh blinds the sight. 43 God alternates the night and the day. In this there is a lesson for the people of understanding. 44 God created every moving thing from water: One crawls on its belly, one walks on two legs, another moves on four. God creates whatsoever He will. Indeed God has power over everything. 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: 'We believe in Allah and the Messenger and obey' But a party of them turn away after this. Those are not 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 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
