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 to Us a gradual concealed withdrawal. 46 And He it is who makes the night a garment for you, and [your] sleep a rest, and causes every [new] day to be a resurrection. 47 And He it is Who sends the winds as good news before His mercy; and We send down pure water from the cloud, 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 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 had willed, We would have raised up in every city a warner. 51 so do not yield to those who deny the truth, but strive with the utmost strenuousness by means of this [Quran, to convey its message to them]. 52 ۞ And it is He Who caused the two joint seas to flow- one is palatable, very sweet, and the other is salty, very bitter; and kept a veil between them and a preventing barrier. 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 They worship besides God things that can neither benefit nor harm them. The unbelievers are defiant against their Lord. 55 But thee We only sent to give glad tidings and admonition. 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 your trust in the All Living who never dies, and exalt with His praise, He is sufficiently aware of His worshipers' sins. 58 Who created the heavens and the earth and all that is between them in six Days, then He mounted the Throne. The Beneficent! Ask anyone informed concerning Him! 59 When it is said to them, "Prostrate to (Allah) Most Gracious!", they say, "And what is (Allah) Most Gracious? Shall we prostrate to that which thou commandest us?" And it increases their flight (from the Truth). ۩ 60
