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 To God belongs the kingdom of the heavens and the earth, and to God shall all things return. 42 Hast thou not seen how Allah wafteth the clouds, then gathereth them, then maketh them layers, and thou seest the rain come forth from between them; He sendeth down from the heaven mountains wherein is hail, and smiteth therewith whom He will, and averteth it from whom He will. The flashing of His lightning all but snatcheth away the sight. 43 It is God who causes night and day to alternate: in this [too,] behold, there is surely a lesson for all who have eyes to see! 44 And Allah created every creature from a sort of water: of them some one crawls upon its belly: another walks on two legs and still another on four; Allah creates whatever He wills for He has power over everything 45 Assuredly We have sent down revelations illuminating: and Allah guideth whomsoever He listeth unto a path straight. 46 And they say: we have believed in Allah and in the apostle and we have obeyed; then there backslide a party of them thereafter: and these 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 Had right been on their side they would have come to him submissively. 49 Are their hearts sick? Do they have doubts or are they afraid that God and His Messenger may do injustice to them? In fact, they, themselves, are unjust. 50
