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 to Allah belongs the dominion of the heavens and the earth, and to Allah is the destination. 42 Beholdest thou not that Allah driveth a cloud along, then combineth it, then maketh it a heap, and then thou beholdest the fine rain come forth from the interstices thereof? And He sendeth down from the heaven mountains wherein is hail, then afflicteth therewith whomsoever He will, and averteth it from whomsoever He will: wellnigh the flash of His lightening taketh away the sights. 43 God alternates the night and the day -- truly, in this there is a lesson for men of insight. 44 And Allah created every animal on earth, from water; so among them is a kind that moves upon its belly; and among them is a kind that moves upon two legs; and among them a kind that moves upon four legs; Allah creates whatever He wills; indeed Allah is Able to do all things. 45 Certainly We have revealed clear communications, and Allah guides whom He pleases to the right way. 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 When they are called to God and His Messenger so that they will judge among them, suddenly, some of them turn away. 48 And if right had been theirs, they would have come to him readily. 49 What, is there sickness in their hearts, or are they in doubt, or do they fear that God may be unjust towards them and His Messenger? Nay, but those -- they are the evildoers. 50
