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 He Who made the night a veil for you, and the sleep a rest, and made the day for getting up. 47 And it is He Who sent the winds giving glad tidings before His mercy; and We sent down purifying water from the sky. 48 To quicken a region that was dead, and to give it as drink to animals We have created and to men in plenty. 49 And We set it forth among them, that they may be admonished, but most men begrudge aught save infidelity. 50 And if We had willed, We would have raised up in each town a warner. 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 the human from water and gave him kindred of blood and of marriage. Your Lord is the Powerful. 54 And they serve besides Allah that which neither profits them nor causes them harm; and the unbeliever is a partisan against his Lord. 55 We have sent thee not, except good tidings to bear, and warning. 56 Proclaim, “I do not ask any fee from you for this, except that whoever wills may take the way to 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 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
