Have you not seen how your Lord lengthens out the shadow? Had He willed, He would have made it constant, but We have made the sun its pilot; 45 Then We draw it back to Us, withdrawing it little by little. 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 sent the winds giving glad tidings before His mercy; and We sent down purifying water from the sky. 48 to revive the barren land and provide water for many creatures, cattle, and people. 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 wanted We could have sent a Prophet to every town. 51 so do not yield to those who deny the truth, but strive with the utmost strenuousness by means of this [Quran, to convey its message to them]. 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 It is He who created man from water, then gave him consanguinity and affinity. Your Lord is omnipotent. 54 Yet they worship, instead of Allah, those who can neither benefit them nor harm them: more than this, the disbeliever has become a helper of every rebel against his Lord. 55 Yet We have not sent you but to give good tidings and to warn. 56 Tell them, "I do not ask of you any recompense for this work: I only ask of the one, who will, to adopt the way of his Lord. 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 whatsoever is in-between them in six days, then He established Himself on the Throne - the Compassionate! so, concerning Him, ask any one informed. 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
