Hast thou not seen how that whatsoever is in the heavens and in the earth extols God, and the birds spreading their wings? Each -- He knows its prayer and its extolling; and God knows the things 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 God turns about the day and the night; surely in that is a lesson for those who have eyes. 44 God has created every beast of water, and some of them go upon their bellies, and some of them go upon two feet, and some of them go upon four; God creates whatever He will; God is powerful over everything. 45 Verily We have sent down revelations and explained them. Allah guideth whom He will unto a straight path. 46 They say, 'We believe in God and the Messenger, and we obey.' Then after that a party of them turn away; those -- they 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 turn aside. 48 However, if the truth be on their side, they come towards the Messenger in all obedience. 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
