Seest thou not that it is Allah Whose praises all beings in the heavens and on earth do celebrate, and the birds (of the air) with wings outspread? Each one knows its own (mode of) prayer and praise. And Allah knows well all that they do. 41 For God's is the kingdom of the heavens and the earth, and the returning is to God. 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 causes the night and the day to succeed each other (i.e. if the day is gone, the night comes, and if the night is gone, the day comes, and so on). Truly, in these things is indeed a lesson for those who have insight. 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 We have sent down Revelations that make the reality quite plain; however, Allah guides to the straight path whomsoever He pleases. 46 They say, "We believe in Allah and in the messenger, and we obey": but even after that, some of them turn away: they are not (really) Believers. 47 And when they are called to [the words of] Allah and His Messenger to judge between them, at once a party of them turns aside [in refusal]. 48 And if the judgement is in their favour, they come towards it willingly. 49 Is there a malady in their hearts, or they are deluded, or afraid that God and His Prophet would be unjust in dealing with them? Not so; they are themselves unjust. 50
