Art thou not aware of thy Sustainer [through His works]? - how He causes the shadow to lengthen [towards the night] when, had He so willed, He could indeed have made it stand still: but then, We have made the sun its guide; 45 Then We draw it back to Us, withdrawing it little by little. 46 And He it is Who makes the Night as a Robe for you, and Sleep as Repose, and makes the Day (as it were) a Resurrection. 47 And He it is Who sends the winds as good news before His mercy; and We send down pure water from the cloud, 48 That We may give life thereby to a dead land, and We give many beasts and men that We have created to drink thereof. 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 If We had willed, We would have raised up in every city a warner. 51 So do not obey the unbelievers, but struggle mightily with it (the Koran). 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 He it is Who has created man from the water, then He has made for him blood relationship and marriage relationship, and your Lord is powerful. 54 They worship besides God things that can neither benefit nor harm them. The unbelievers are defiant against their Lord. 55 We did not send you but 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 Also trust in the Living One who never dies and glorify Him with His praise. He has sufficient knowledge of the sins 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 When you say to them: "Bow before Ar-Rahman," they say: "What is Ar-Rahman? Should we adore whoever you ask us to?" And their aversion increases further. ۩ 60
