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 withdraw it to Us a gradual concealed withdrawal. 46 It is He who made the night a covering for you; and made sleep for rest, the day for rising. 47 And He it is Who sendeth the winds, glad tidings heralding His mercy, and We send down purifying water from the sky, 48 to revive the barren land and provide water for many creatures, cattle, and people. 49 We have explained it to them in diverse ways, so that they may take heed, but most persist in their ingratitude. 50 And if We had willed, We could have sent into every city a warner. 51 So do not listen to unbelievers, and strive against them with greater effort. 52 ۞ And it is He Who has let free the two seas (kinds of water), one palatable and sweet, and the other salt and bitter, and He has set a barrier and a complete partition between them. 53 It is He who has created human beings from water and He has granted them the ties of blood as well as marriage. Your 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 Yet We have not sent you but to give good tidings and to warn. 56 Tell them, "I do not ask of you any recompense for this work: I only ask of the one, who will, to adopt the way of his Lord. 57 Have trust in God the Living, who will never die, and sing His hallelujas; for He is well aware of the sins of His creatures. 58 (It is) He who, in six days created the heavens and the earth and all that lies between them, and then He willed to the Throne. The Merciful; ask about Him from he who knows Him. 59 When it is said to them, "Prostrate to (Allah) Most Gracious!", they say, "And what is (Allah) Most Gracious? Shall we prostrate to that which thou commandest us?" And it increases their flight (from the Truth). ۩ 60
