Have you not seen how your Lord lengthens the shadows? Had He pleased, He could have made them constant; then We placed the sun as an indicator for them, 45 thereafter We seize it to Us withdrawing it gently. 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 And He it is Who sends the winds as heralds of glad tidings, going before His mercy, and We send down pure water from the sky,- 48 so that We might revive a dead land, and give to drink of it, of that We created, cattle and men a many. 49 We have indeed turned it about them, so that they remember; yet most people refuse all except disbelief. 50 And if We had willed, We could have sent into every city a warner. 51 So obey not the unbelievers, but struggle with them thereby mightily. 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 It is He who has created the human being from water to have relationships of both lineage and wedlock. Your Lord has all power. 54 Yet they worship besides God that which can neither benefit them nor harm them. One who denies the truth is a helper [of evil] against his Lord. 55 We have sent you for no other reason but to be a bearer of glad news and warning. 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 And rely upon the Ever-Living who does not die, and exalt [Allah] with His praise. And sufficient is He to be, with the sins of His servants, Acquainted - 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 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
