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 The kingdom of the heavens and the earth belongs to Allah alone, and all shall have to return to Him. 42 Art thou not aware that it is God who causes the clouds to move onward, then joins them together, then piles them up in masses, until thou can see rain come forth from their midst? And He it is who sends down from the skies, by degrees, mountainous masses [of clouds] charged with hail, striking therewith whomever He wills and averting it from whomever He wills, [the while] the flash of His lightning well-nigh deprives [men of their] sight! 43 It is God who alternates night and day. There is surely a lesson in this for men of sight. 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 Assuredly We have sent down revelations illuminating: and Allah guideth whomsoever He listeth unto a path straight. 46 They say: 'We believe in Allah and the Messenger and obey' But a party of them turn away after this. Those 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 are averters. 48 And if the truth be on their side, they come to him quickly, obedient. 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
