Have you not seen how your Lord lengthens out the shadow? He could have kept it motionless if He liked. Yet We make the sun its pilot to show the way. 45 Then We draw it back to Us, withdrawing it little by little. 46 And it is He who hath made for you the night a covering, and the sleep repose, and hath made the day a resurrection. 47 And it is He Who sends the winds as heralds of glad tidings, going before His Mercy (rain), and We send down pure water from the sky, 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 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 Now had We so willed, We could have [continued as before and] raised up a [separate] warner in every single community: 51 So obey not the disbelievers, but strive against them herewith with a great endeavour. 52 ۞ And He it is Who has made two seas to flow freely, the one sweet that subdues thirst by its sweetness, and the other salt that burns by its saltness; and between the two He has made a barrier and inviolable obstruction. 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 Yet do they worship, besides Allah, things that can neither profit them nor harm them: and the Misbeliever is a helper (of Evil), against his own Lord! 55 We have sent you only as a bearer of glad tidings and as a warner. 56 Say: 'I do not ask of you a wage for this, except for him who wishes to take to his Lord a way.' 57 Put your trust in the All Living who never dies, and exalt with His praise, He is sufficiently aware of His worshipers' 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 When they are told, "Prostrate yourselves before the Gracious One," they ask, "Who is this Gracious One? Shall we prostrate ourselves before whatever you will?" This increases their aversion. ۩ 60
