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 withdrew it to Us, a gradual withdrawal. 46 And it is He who has made the night for you as clothing and sleep [a means for] rest and has made the day a resurrection. 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 In order that We may revive a dead city with it, and give it to the many beasts and men that We have created, to drink. 49 And We distribute it among them in various ways that they may ponder and reflect; yet most men disdain everything but denial and thanklessness. 50 And if We had willed, We would have raised up in each town a warner. 51 So do not obey the unbelievers, but struggle mightily with it (the Koran). 52 ۞ It is He who has joined the two seas; one palatable and sweet, the other bitterly salty and has established a barrier between them as a partition. 53 And it is He who created of water a mortal, and made him kindred of blood and marriage; thy Lord is All-powerful. 54 And yet they worship besides God what cannot bring them gain or do them harm. The unbeliever has always been an auxiliary against his Lord. 55 And We have not sent you, [O Muhammad], except as a bringer of good tidings and a warner. 56 Say: 'I demand of you no wage for this except for he who wishes to take the Path to his Lord' 57 And put thy trust in Him Who lives and dies not; and celebrate his praise; and enough is He to be acquainted with the faults of His servants;- 58 He who created the heavens and the earth and what is between them in six days and then established Himself above the Throne - the Most Merciful, so ask about Him one well informed. 59 When it is said to them. "Prostrate yourselves before the Merciful," they retort, "What is the Merciful? Would you have us prostrate ourselves before whomsoever you will?" And this invitation only helps to increase their hatred all the more. ۩ 60
