Have you not seen how your Lord lengthens the shadows? Had He pleased, He could have made them constant; then We placed the sun as an indicator for them, 45 We then gradually withdraw it towards Us. 46 It is He who has made the night as a covering for you, sleep as a rest for you, and the day for you to rise again. 47 It is He who sends the winds to you with the glad news of His mercy and who sends purifying rain from the sky 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 have indeed turned it about them, so that they remember; yet most people refuse all except disbelief. 50 Had it been Our Will, We could have sent a warner to every centre of population. 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 ۞ It is He Who has let free the two bodies of flowing water: One palatable and sweet, and the other salt and bitter; yet has He made a barrier between them, a partition that is forbidden to be passed. 53 And it is He, Who created man from water: then from him He caused two kinds of kindred, by blood and by marriage: your Lord is AI I-Powerful. 54 And they serve besides Allah that which neither profits them nor causes them harm; and the unbeliever is a partisan against his Lord. 55 And We have not sent you but as a giver of good news and as a warner. 56 Say, "I do not ask of you for it any payment - only that whoever wills might take to his Lord a way." 57 Hence, place thy trust in the Living One who dies not, and extol His limitless glory and praise: for none is as aware as His creatures' sins as He 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
