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 He it is who sends forth the winds as a glad tiding of His coming grace; and [thus, too,] We cause pure water to descend from the skies, 48 That We may bring to life thereby a dead land and give it as drink to those We created of numerous livestock and men. 49 We present the same phenomenon over and over again before them so that they may learn a lesson from it; but most people decline to adopt any other attitude than of disbelief and ingratitude. 50 And if We had pleased We would certainly have raised a warner in every town. 51 So obey not the unbelievers, but struggle with them thereby mightily. 52 ۞ It is He who made two bodies of water flow side by side, one fresh (and) sweet, the other brine (and) bitter, and has placed an interstice, a barrier between them. 53 And He it is who out of this [very] water has created man, and has endowed him with [the consciousness of] descent and marriage-tie: for thy Sustainer is ever infinite in His power. 54 Yet they worship instead of Allah that which can neither benefit them nor hurt them. The disbeliever was ever a partisan against his Lord. 55 We have sent you for no other reason but to be a bearer of glad news and warning. 56 Tell them: "I do not ask any recompense of you for this other than (urging) whoever likes may take the way to his Lord." 57 Put thy trust in the Living God, the Undying, and proclaim His praise. Sufficiently is He aware of His servants sins 58 He created the heavens and the earth and all that lies between them in six spans then assumed His authority. He is the benevolent: Ask those who are well-informed. 59 When it is said to them. "Prostrate yourselves before the Merciful," they retort, "What is the Merciful? Would you have us prostrate ourselves before whomsoever you will?" And this invitation only helps to increase their hatred all the more. ۩ 60
