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 thereafter We seize it to Ourselves, drawing it gently. 46 It is He who has made the night as a covering for you, sleep as a rest for you, and the day for you to rise again. 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 Had it been Our Will, We could have sent a warner to every centre of population. 51 So do not obey the disbelievers, and strive against them with the Qur'an a great striving. 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 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 they serve, apart from God, what neither profits them nor hurts them; and the unbeliever is ever a partisan against his Lord. 55 O Muhammad, We have sent you only to proclaim good tidings and to give warning. 56 Tell them, "I ask no recompense for my preaching to you, except the fact that whoever wants should choose the way of God." 57 Have trust in God the Living, who will never die, and sing His hallelujas; for He is well aware of the sins of His creatures. 58 it is He who created the heavens and the earth and all that is between them in six Days [periods], then settled Himself on the throne -- the Gracious One. Ask any informed person about Him. 59 When they are told, "Prostrate yourselves before the Gracious One," they ask, "Who is this Gracious One? Shall we prostrate ourselves before whatever you will?" This increases their aversion. ۩ 60
