See you not (O Muhammad SAW) that Allah, He it is Whom glorify whosoever is in the heavens and the earth, and the birds with wings out-spread (in their flight). Of each one He (Allah) knows indeed his Salat (prayer) and his glorification, [or everyone knows his Salat (prayer) and his glorification], and Allah is All-Aware of what they do. 41 For God's is the kingdom of the heavens and the earth, and the returning is to God. 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 Allah turneth the night and the day over and over; verily therein is a lesson for men of insight. 44 Allah has created every [living] creature from water. And of them are those that move on their bellies, and of them are those that walk on two legs, and of them are those that walk on four. Allah creates what He wills. Indeed, Allah is over all things competent. 45 And We indeed sent down clear verses; and Allah may guide whomever He wills to the Straight Path. 46 And they say: We believe in Allah and the messenger, and we obey; then after that a faction of them turn away. Such are not believers. 47 When they are summoned to Allah and His messenger, in order that He may judge between them, behold some of them decline (to come). 48 But if the right is on their side, they come to him with all submission. 49 Is there a sickness in their hearts, or are they full of doubt? Or do they fear that God and His Messenger will be unjust to them? The truth is that they themselves are wrongdoers. 50
