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 draw it toward Us with an easy drawing. 46 It is He who made the night a covering for you; and made sleep for rest, the day for rising. 47 And He it is Who sendeth the winds, glad tidings heralding His mercy, and We send down purifying water from the sky, 48 so that We may bring life to a dead land; and slake the thirst of Our creation; cattle and men, in great numbers. 49 And indeed, many times have We repeated [all] this unto men, so that they might take it to heart: but most men refuse to be aught but ingrate. 50 If We willed, We could have sent a Herald of Warning to every village. 51 So do not obey the unbelievers, but struggle mightily with it (the Koran). 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 And it is He who hath created man from water, and then made for him kinship by blood and marriage. And thy Lord is ever potent. 54 And yet, some people worship, instead of God, things that can neither benefit them nor harm them: thus, he who denies the truth does indeed turn his back on his Sustainer! 55 And We have not sent you, [O Muhammad], except as a bringer of good tidings and a warner. 56 Say: I ask of you no reward for this, save that whoso will may choose a way unto his Lord. 57 And rely on the Ever-living Who dies not, and celebrate His praise; and Sufficient is He as being aware of the faults of His servants, 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 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
