Have you not considered your Lord - how He extends the shadow, and if He willed, He could have made it stationary? Then We made the sun for it an indication. 45 We then gradually withdraw it towards Us. 46 And it is He Who makes the night a covering for you, and the sleep (as) repose, and makes the day Nushur (i.e. getting up and going about here and there for daily work, etc. after one's sleep at night or like resurrection after one's death). 47 And He it is Who sends the winds as heralds of glad tidings, going before His mercy, and We send down pure water from the sky,- 48 so that We may bring life to a dead land; and slake the thirst of Our creation; cattle and men, in great numbers. 49 We send them rain from time to time so that they may take heed. Many people have responded, but ungratefully. 50 And if We had willed, We could have sent into every city 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 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 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 And We sent thee but as a bearer of glad tidings and warner. 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 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 it is He who created the heavens and the earth and all that is between them in six Days [periods], then settled Himself on the throne -- the Gracious One. Ask any informed person about Him. 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
