Have you not seen how your Lord lengthens out the shadow? He could have kept it motionless if He liked. Yet We make the sun its pilot to show the way. 45 We then gradually withdraw it towards Us. 46 And it is He who has made the night for you as clothing and sleep [a means for] rest and has made the day a resurrection. 47 And it is He Who sent the winds giving glad tidings before His mercy; and We sent down purifying water from the sky. 48 so that He may revive the dead land, and quench the thirst of many of His creatures from among beasts and men. 49 We have indeed turned it about them, so that they remember; yet most people refuse all except disbelief. 50 And if We had willed, We could have sent into every city a warner. 51 So do not obey the unbelievers, but struggle mightily with it (the Koran). 52 ۞ It was He who let forth the two seas, this one is palatably sweet and this salt, a bitter taste, and He set a barrier between them, and a refuge which is forbidden. 53 And it is He who created of water a mortal, and made him kindred of blood and marriage; thy Lord is All-powerful. 54 But they worship rather than Allah that which does not benefit them or harm them, and the disbeliever is ever, against his Lord, an assistant [to Satan]. 55 Yet [withal, O Prophet,] We have sent thee only as a herald of glad tidings and a warner. 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 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 He Who created the heavens and the earth and all that is between, in six days, and is firmly established on the Throne (of Authority): Allah Most Gracious: ask thou, then, about Him of any acquainted (with such things). 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
