Have you not seen how your Lord lengthens the shadows? Had He pleased, He could have made them constant; then We placed the sun as an indicator for them, 45 Then We draw it in towards Ourselves,- a contraction by easy stages. 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 sendeth forth the winds as a herald before His mercy and We send down from the heaven water pure. 48 so, that with it We revive dead lands and provide drink for the cattle and the human We created. 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 it been Our Will, We could have sent a warner to every centre of population. 51 So do not follow the unbelievers, and strive against them a mighty striving with it. 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 He it is Who hath created man from water, and hath appointed for him kindred by blood and kindred by marriage; for thy Lord is ever Powerful. 54 They worship besides God things that can neither benefit nor harm them. The unbelievers are defiant against their Lord. 55 We have sent you for no other reason but to be a bearer of glad news and warning. 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 thou in the Living One Who dieth not, and hymn His praise. He sufficeth as the Knower of His bondmen's sins, 58 who created the heavens and the earth, and what between them is, in six days, then sat Himself upon the Throne, the All-compassionate: ask any informed of Him! 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
