Do you not see how your Lord stretches the shadow? Had it been His will, He could have made it constant. Then He appointed the sun to be a guide to it; 45 Then We withdraw it unto Us, a gradual withdrawal? 46 And it is He Who made the night a veil for you, and the sleep a rest, and made the day for getting up. 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 That We may give life thereby to a dead land and give it for drink, out of what We have created, to cattle and many people. 49 And indeed We kept cycles of water among them that they may remember; so most men did not accept, except to be ungrateful. 50 Had We pleased We could have raised a warner in every town. 51 So do not listen to unbelievers, and strive against them with greater effort. 52 ۞ And He it is Who hath given independence to the two seas (though they meet); one palatable, sweet, and the other saltish, bitter; and hath set a bar and a forbidding ban between them. 53 It is He who has created human beings from water and He has granted them the ties of blood as well as marriage. Your Lord is all powerful. 54 Yet they (the unbelievers) worship, other than Allah, that which can neither benefit nor harm them. Surely, the unbeliever is ever a partisan against his Lord. 55 We have sent thee not, except good tidings to bear, and warning. 56 Say, "I do not ask of you for it any payment - only that whoever wills might take to his Lord a way." 57 Put your trust in the One who is the Ever-Living [God], who never dies, and glorify Him with His praise. He is fully aware of the sins of His servants; 58 who created the heavens and the earth, and what between them is, in six days, then sat Himself upon the Throne, the All-compassionate: ask any informed of Him! 59 Yet when they [who are bent on denying the truth are told, "Prostrate yourselves before the Most Gracious" they are wont to ask, "And [who and] what is the Most Gracious? Are we to prostrate ourselves before whatever thou biddest us [to worship]?" - and so [thy call] but increases their aversion, ۩ 60
