Have you not seen that your Lord increases the shadow. Had He wanted He would have made it stationary], and has made the sun their guide. 45 Then We withdraw it to Us a gradual concealed withdrawal. 46 And it is He who hath made for you the night a covering, and the sleep repose, and hath made the day a resurrection. 47 And it is He who has loosed the winds, bearing good tidings before His mercy; and We sent down from heaven pure water 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 We have distributed the (water) amongst them, in order that they may celebrate (our) praises, but most men are averse (to aught) but (rank) ingratitude. 50 If We had willed, We would have raised up in every city a warner. 51 So obey not the disbelievers, but strive against them herewith with a great endeavour. 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 And it is He who has created from water a human being and made him [a relative by] lineage and marriage. And ever is your Lord competent [concerning creation]. 54 And they worship such, other than Allah, which neither benefit nor hurt them; and the disbeliever helps the devil instead of his Lord. 55 We have sent you only as a bearer of glad tidings and as a warner. 56 Say: I do not ask you aught in return except that he who will, may take the way to his Lord. 57 And trust thou in the Living One who dieth not, and hallow His praise; it sufficeth that He of the sins of His bondmen is Aware. 58 Who created the heavens and the earth and all that is between them in six Days, then He mounted the Throne. The Beneficent! Ask anyone informed concerning Him! 59 When it is said to them: 'Prostrate yourselves before the Merciful', they ask: 'And what is the Merciful? Shall we prostrate ourselves to whatever you bid us' And it increases their aversion. ۩ 60
