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 It is He who has appointed the night a mantle for you and sleep for a rest. The day He has appointed for rising. 47 And it is He who sendeth forth the winds as a herald before His mercy and We send down from the heaven water pure. 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 And We have distributed the (water) amongst them, in order that they may celebrate (our) praises, but most men are averse (to aught) but (rank) ingratitude. 50 If We had willed, We would have raised up in every city a warner. 51 So do not follow the unbelievers, and strive against them a mighty striving with it. 52 ۞ It is He Who has let free the two bodies of flowing water: One palatable and sweet, and the other salt and bitter; yet has He made a barrier between them, a partition that is forbidden to be passed. 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 yet, some people worship, instead of God, things that can neither benefit them nor harm them: thus, he who denies the truth does indeed turn his back on his Sustainer! 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 of you for it any payment - only that whoever wills might take to his Lord a way." 57 And rely on the Ever-living Who dies not, and celebrate His praise; and Sufficient is He as being aware of the faults of His servants, 58 He who created the heavens and the earth and what is between them in six days and then established Himself above the Throne - the Most Merciful, so ask about Him one well informed. 59 When it is said to them: 'Prostrate yourselves before the Merciful', they ask: 'And what is the Merciful? Shall we prostrate ourselves to whatever you bid us' And it increases their aversion. ۩ 60
