Have you not seen that your Lord increases the shadow. Had He wanted He would have made it stationary], and has made the sun their guide. 45 Then We withdraw it to Us a gradual concealed withdrawal. 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 It is He who loosens the winds, bearing glad tidings before the Hands of His Mercy, and We have sent down pure water from the heaven, 48 to revive the barren land and provide water for many creatures, cattle, and people. 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 Had We willed, We would have raised up a separate Warner in each habitation. 51 So obey not the disbelievers, but strive against them (by preaching) with the utmost endeavour, with it (the Quran). 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 He it is Who has created man from the water, then He has made for him blood relationship and marriage relationship, and your Lord is powerful. 54 And they serve, apart from God, what neither profits them nor hurts them; and the unbeliever is ever a partisan against his Lord. 55 Yet [withal, O Prophet,] We have sent thee only as a herald of glad tidings and a warner. 56 Say, "I do not ask you for any recompense for this except that anyone who so wishes should take the right path to his Lord." 57 Have trust in God the Living, who will never die, and sing His hallelujas; for He is well aware of the sins of His creatures. 58 Who created the heavens and the earth and what is between them in six periods, and He is firmly established on the throne of authority; the Beneficent Allah, so ask respecting it one aware. 59 When they are told, "Prostrate yourselves before the Gracious One," they ask, "Who is this Gracious One? Shall we prostrate ourselves before whatever you will?" This increases their aversion. ۩ 60
