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 And for Allah only is the kingship of the heavens and the earth; and towards 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 It is Allah Who alternates the Night and the Day: verily in these things is an instructive example for those who have vision! 44 Allah created everything that walks from water. Some creep upon their bellies, others walk on two feet, and others walk on four. Allah creates whatever He will. Allah is Powerful over everything. 45 Now We have sent down signs making all clear; God guides whomsoever He will to a straight path. 46 And they say: We believe in Allah and the messenger, and we obey; then after that a faction of them turn away. Such are not believers. 47 And when they are called to Allah (i.e. His Words, the Quran) and His Messenger (SAW), to judge between them, lo! a party of them refuse (to come) and turn away. 48 but if the truth happens to be to their liking, they are quite willing to accept it! 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
