Have you not considered (the work of) your Lord, how He extends the shade? And if He had pleased He would certainly have made it stationary; then We have made the sun an indication of it 45 thereafter We seize it to Us withdrawing it gently. 46 It is He who made the night a mantle for you, and sleep for repose; and made the day a time for rising. 47 And it is He Who sends the winds as heralds of glad tidings, going before His Mercy (rain), and We send down pure water from the sky, 48 to revive the barren land and provide water for many creatures, cattle, and people. 49 And We distribute it among them in various ways that they may ponder and reflect; yet most men disdain everything but denial and thanklessness. 50 Had We pleased We could have raised a warner in every town. 51 So obey not the disbelievers, but strive against them (by preaching) with the utmost endeavour, with it (the Quran). 52 ۞ And it is He Who has let free the two seas (kinds of water), one palatable and sweet, and the other salt and bitter, and He has set a barrier and a complete partition between them. 53 And it is He Who created man from water, then appointed relatives and in-laws for him; and your Lord is All Able. 54 And they worship such, other than Allah, which neither benefit nor hurt them; and the disbeliever helps the devil instead of his Lord. 55 We have sent thee not, except good tidings to bear, and warning. 56 Say: "For this, no reward do I ask of you - [no reward] other than that he who so wills may unto his Sustainer find a way!" 57 And trust the Living One Who will never die, and praising Him proclaim His Purity; and He is Sufficient upon the sins of His bondmen, All Aware. 58 it is He who created the heavens and the earth and all that is between them in six Days [periods], then settled Himself on the throne -- the Gracious One. Ask any informed person about Him. 59 When you say to them: "Bow before Ar-Rahman," they say: "What is Ar-Rahman? Should we adore whoever you ask us to?" And their aversion increases further. ۩ 60
