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 We then gradually withdraw it towards Us. 46 It is He who made the night a mantle for you, and sleep for repose; and made the day a time for rising. 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 give life thereby to a dead land, and We give to drink thereof many of the cattle and men that We had created. 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 If We willed, We could have sent a Herald of Warning to every village. 51 Therefore listen not to the Unbelievers, but strive against them with the utmost strenuousness, with the (Qur'an). 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 the human from water and gave him kindred of blood and of marriage. Your Lord is the Powerful. 54 And yet they worship, besides Allah, that which can neither benefit them nor hurt them; and the infidel is ever an aider of the devil against his Lord. 55 We have sent you for no other reason but to be a bearer of glad news and warning. 56 Say: "No reward do I ask of you for this (that which I have brought from my Lord and its preaching, etc.), save that whosoever wills, may take a Path to his Lord. 57 And put your trust (O Muhammad SAW) in the Ever Living One Who dies not, and glorify His Praises, and Sufficient is He as the All-Knower of the sins of His slaves; 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 When they are told to prostrate themselves before the Beneficent God, they say, "Who is the Beneficent God? Why should we prostrate ourselves before the one whom you have commanded us to?" This only increases their rebelliousness. ۩ 60
