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 And it is Allah Who has ordained the night as a garment for you, and the sleep as a repose of death, and the day as the time of return to life. 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 We may bring to life thereby a dead land and give it as drink to those We created of numerous livestock and men. 49 And indeed We kept cycles of water among them that they may remember; so most men did not accept, except to be ungrateful. 50 If We willed, We could have sent a Herald of Warning to every village. 51 So do not obey the disbelievers, and strive against them with the Qur'an a great striving. 52 ۞ And it is He who let forth the two seas, this one Sweet, grateful to taste, and this salt, bitter to the tongue, and He set between them a barrier, and a ban forbidden. 53 And He it is Who hath created man from water, and hath appointed for him kindred by blood and kindred by marriage; for thy Lord is ever Powerful. 54 They worship besides God things that can neither benefit nor harm them. The unbelievers are defiant against their Lord. 55 Yet We have not sent you but to give good tidings and to warn. 56 Say: I ask of you no reward for this, save that whoso will may choose a way unto 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 who created the heavens and the earth, and what between them is, in six days, then sat Himself upon the Throne, the All-compassionate: ask any informed of 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
