Do you not observe that all those who are in the heavens and the earth, and the birds with outspread wings, glorify Allah? Each one knows the mode of its prayer and glorification, and Allah has full knowledge of all they do. 41 And unto Allah belongeth the Sovereignty of the heavens and the earth, and unto Allah is the journeying. 42 Have you not seen that God drives the clouds, then joins them together and puts them fold on fold. Then you see the rain fall through them; and He sends down hail from the sky where there are mountains of it, and strikes those with it whom He will, and wards it off from whomsoever He please. His lightning could snatch away their eyes. 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 Allah hath created every moving creature of water; of them is one that walketh upon his belly; and of them is one that walketh upon its two feet; and of them is one that walketh upon four. Allah createth whatsoever He listeth; verily Allah is over everything Potent. 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 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 But if the right is with them, they come to him willingly with submission. 49 Are their hearts afflicted with the disease (of hypocrisy)? Or, are they in doubt? Or, do they fear that Allah and His Messenger will be unjust to them? In fact, they themselves are unjust. 50
