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 and then, [after having caused it to lengthen,] We draw it in towards Ourselves with a gradual drawing-in. 46 And He it is Who maketh night a covering for you, and sleep repose, and maketh day a resurrection. 47 And it is He Who sends the winds as heralds of glad tidings, going before His Mercy (rain), and We send down pure water from the sky, 48 That with it We may give life to a dead land, and slake the thirst of things We have created,- cattle and men in great numbers. 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 hence, do not defer to [the likes and dislikes of] those who deny the truth, but strive hard against them, by means of this [divine writ,] with utmost striving. 52 ۞ And it is He Who has let free the two seas (kinds of water), one palatable and sweet, and the other salt and bitter, and He has set a barrier and a complete partition between them. 53 And it is He who has created from water a human being and made him [a relative by] lineage and marriage. And ever is your Lord competent [concerning creation]. 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 And We have sent thee (O Muhammad) only as a bearer of good tidings and a warner. 56 Say: I do not ask you aught in return except that he who will, may take the way to his Lord. 57 And put thy trust in Him Who lives and dies not; and celebrate his praise; and enough is He to be acquainted with the faults of His servants;- 58 The One Who created the heavens and the earth and all that is between them in six days, then befitting His Majesty, established Himself upon the Throne (of control); the Most Gracious – therefore ask the one who knows, concerning Him! 59 Yet when they [who are bent on denying the truth are told, "Prostrate yourselves before the Most Gracious" they are wont to ask, "And [who and] what is the Most Gracious? Are we to prostrate ourselves before whatever thou biddest us [to worship]?" - and so [thy call] but increases their aversion, ۩ 60
