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 thereafter We seize it to Us withdrawing it gently. 46 It is He who made the night a covering for you; and made sleep for rest, the day for rising. 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 so that He may revive the dead land, and quench the thirst of many of His creatures from among beasts and men. 49 We send them rain from time to time so that they may take heed. Many people have responded, but ungratefully. 50 And had We willed, We would have raised a warner in every town. 51 So do not follow the unbelievers, and strive against them a mighty striving with it. 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 And yet they worship, besides Allah, that which can neither benefit them nor hurt them; and the infidel is ever an aider of the devil against his Lord. 55 And We sent thee but as a bearer of glad tidings and warner. 56 Say: "For this, no reward do I ask of you - [no reward] other than that he who so wills may unto his Sustainer find a way!" 57 And trust the Living One Who will never die, and praising Him proclaim His Purity; and He is Sufficient upon the sins of His bondmen, All Aware. 58 He created the heavens and the earth and all that lies between them in six spans then assumed His authority. He is the benevolent: Ask those who are well-informed. 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
