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 And unto Allah belongeth the Sovereignty of the heavens and the earth, and unto Allah is the journeying. 42 Do you not see that Allah drives along the clouds, then gathers them together, then piles them up, so that you see the rain coming forth from their midst? And He sends down of the clouds that are (like) mountains wherein is hail, afflicting therewith whom He pleases and turning it away from whom He pleases; the flash of His lightning almost takes away the sight. 43 He alternates the day and the night: there is indeed a lesson in it for those who have observing eyes. 44 And Allah has created every animal from water: of them there are some that creep on their bellies; some that walk on two legs; and some that walk on four. Allah creates what He wills for verily Allah has power over all things. 45 We have surely sent down clear signs. It is God who guides whom He will to the path that is straight. 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 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
