Art thou not aware of thy Sustainer [through His works]? - how He causes the shadow to lengthen [towards the night] when, had He so willed, He could indeed have made it stand still: but then, We have made the sun its guide; 45 Then We withdraw it to Us a gradual concealed withdrawal. 46 And it is He who has made the night for you as clothing and sleep [a means for] rest and has made the day a resurrection. 47 And He it is Who sends the winds as good news before His mercy; and We send down pure water from the cloud, 48 That We may bring to life thereby a dead land and give it as drink to those We created of numerous livestock and men. 49 We send them rain from time to time so that they may take heed. Many people have responded, but ungratefully. 50 Had We pleased We could have raised a warner in every town. 51 So obey not the unbelievers, but struggle with them thereby mightily. 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 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 besides Allah that which neither profits them nor causes them harm; and the unbeliever is a partisan against his Lord. 55 We have sent thee not, except good tidings to bear, and warning. 56 Say: I ask of you no reward for this, save that whoso will may choose a way unto 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 you say to them: "Bow before Ar-Rahman," they say: "What is Ar-Rahman? Should we adore whoever you ask us to?" And their aversion increases further. ۩ 60
