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 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 And Allah created every creature from a sort of water: of them some one crawls upon its belly: another walks on two legs and still another on four; Allah creates whatever He wills for He has power over everything 45 We have indeed sent down (in this Quran) manifest Ayat (proofs, evidences, verses, lessons, signs, revelations, lawful and unlawful things, and the set boundries of Islamic religion, etc. that make things clear showing the Right Path of Allah). And Allah guides whom He wills to a Straight Path (i.e. to Allah's religion of Islamic Monotheism). 46 They say they believe in God and the Prophet, and have come to believe, yet a section of them turns back even after this; and these are not believers. 47 When they are called to God and His Messenger that he may judge between them, lo, a party of them are swerving aside; 48 However, if the truth be on their side, they come towards the Messenger in all obedience. 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
