Have you not seen how your Lord spread the shadow. If He willed, He could have made it still then We have made the sun its guide [i.e. after the sunrise, it (the shadow) squeezes and vanishes at midnoon and then again appears in the afternoon with the decline of the sun, and had there been no sun light, there would have been no shadow]. 45 Then We withdraw it unto Us, a gradual withdrawal? 46 It is He who appointed the night for you to be a garment and sleep for a rest, and day He appointed for a rising. 47 It is He who sends the winds to you with the glad news of His mercy and who sends purifying rain from the sky 48 That We may quicken thereby a dead land, and We give drink thereof to that which We have created of cattle and human beings many. 49 And indeed, many times have We repeated [all] this unto men, so that they might take it to heart: but most men refuse to be aught but ingrate. 50 Had We willed, We would have raised up a separate Warner in each habitation. 51 so do not yield to those who deny the truth, but strive with the utmost strenuousness by means of this [Quran, to convey its message to them]. 52 ۞ And it is He who has released [simultaneously] the two seas, one fresh and sweet and one salty and bitter, and He placed between them a barrier and prohibiting partition. 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 Yet they (the unbelievers) worship, other than Allah, that which can neither benefit nor harm them. Surely, the unbeliever is ever a partisan against his Lord. 55 And We have sent you (O Muhammad SAW) only as a bearer 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 And trust thou in the Living One Who dieth not, and hymn His praise. He sufficeth as the Knower of His bondmen's sins, 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 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
