Have you not seen how your Lord lengthens out the shadow? Had He willed, He would have made it constant, but We have made the sun its pilot; 45 Then We take it to Ourselves, taking little by little. 46 It is He who made the night a covering for you; and made sleep for rest, the day for rising. 47 It is He who sends the winds as heralds of His mercy and We send down pure water from the sky, 48 That We may give life thereby to a dead land, and We give to drink thereof many of the cattle and men that We had created. 49 We have indeed turned it about amongst them, so that they may remember; yet most men refuse all but unbelief. 50 Now had We so willed, We could have [continued as before and] raised up a [separate] warner in every single community: 51 So do not follow the unbelievers, and strive against them a mighty striving with it. 52 ۞ AND HE it is who has given freedom of movement to the two great bodies of water - the one sweet and thirst-allaying, and the other salty and bitter - and yet has wrought between them a barrier and a forbidding ban. 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 And they serve, apart from God, what neither profits them nor hurts them; and the unbeliever is ever a partisan against his Lord. 55 O Muhammad, We have sent you only to proclaim good tidings and to give warning. 56 Say: "No reward do I ask of you for it but this: that each one who will may take a (straight) 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 Who created the heavens and the earth and all that is between them in six Days, then He mounted the Throne. The Beneficent! Ask anyone informed 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
