Do you not see how your Lord stretches the shadow? Had it been His will, He could have made it constant. Then He appointed the sun to be a guide to it; 45 Then We draw it back to Us, withdrawing it little by little. 46 And He it is Who maketh night a covering for you, and sleep repose, and maketh day a resurrection. 47 And it is He, Who drives the winds to be the harbingers of His mercy: then He sends down pure water from the sky 48 so that We might revive a dead land, and give to drink of it, of that We created, cattle and men a many. 49 And indeed We kept cycles of water among them that they may remember; so most men did not accept, except to be ungrateful. 50 Had We pleased We could have raised a warner in every town. 51 So do not obey the unbelievers, but struggle mightily with it (the Koran). 52 ۞ And it is He who has released [simultaneously] the two seas, one fresh and sweet and one salty and bitter, and He placed between them a barrier and prohibiting partition. 53 It is He Who has created man from water: then has He established relationships of lineage and marriage: for thy Lord has power (over all things). 54 Yet they (the unbelievers) worship, other than Allah, that which can neither benefit nor harm them. Surely, the unbeliever is ever a partisan against his Lord. 55 We have sent you for no other reason but to be a bearer of glad news and warning. 56 Tell them: "I do not ask any recompense of you for this other than (urging) whoever likes may take the way to his Lord." 57 And rely on the Ever-living Who dies not, and celebrate His praise; and Sufficient is He as being aware of the faults of His servants, 58 He who has created the heavens and the earth and all that is between them in six aeons, and is established on the throne of His almightiness; the Most Gracious! Ask, then, about Him, [the] One who is [truly] aware. 59 But when they are told, 'Bow yourselves to the All-merciful,' they say, 'And what is the All-merciful? Shall we bow ourselves to what thou biddest us?' And it increases them in aversion. ۩ 60
