Hast thou not seen how that whatsoever is in the heavens and in the earth extols God, and the birds spreading their wings? Each -- He knows its prayer and its extolling; and God knows the things they do. 41 And to Allah belongs the sovereignty of the heavens and the earth, and to Allah is the return (of all). 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 God alternates the night and the day. In this there is a lesson for the people of understanding. 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 INDEED, from on high have We bestowed messages clearly showing the truth; but God guides onto a straight way [only] him that wills [to be guided]. 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 appeal unto Allah and His messenger to judge between them, lo! a faction of them are averse; 48 But if right had been with them they would have come unto him willingly. 49 Is it that there is a disease in their hearts? or do they doubt, or are they in fear, that Allah and His Messenger will deal unjustly with them? Nay, it is they themselves who do wrong. 50
