Hast thou not observed thine lord - how He hath stretched out the shadow? And if He had willed He would have made it still. Then We have made the sun for it an indication. 45 thereafter We seize it to Us withdrawing it gently. 46 And He it is who makes the night a garment for you, and [your] sleep a rest, and causes every [new] day to be a resurrection. 47 And it is He Who sends the winds as heralds of glad tidings, going before His Mercy (rain), and We send down pure water from the sky, 48 To quicken a region that was dead, and to give it as drink to animals We have created and to men in plenty. 49 We have explained it to them in diverse ways, so that they may take heed, but most persist in their ingratitude. 50 And if We had pleased We would certainly have raised a warner in 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 ۞ It is He who released the two bodies of flowing water, one sweet and fresh and the other salty and bitter, and set up an insurmountable barrier between them. 53 And it is He who created the human from water and gave him kindred of blood and of marriage. Your Lord is the Powerful. 54 And yet they worship besides God what cannot bring them gain or do them harm. The unbeliever has always been an auxiliary against his Lord. 55 O Muhammad, We have sent you only to proclaim good tidings and to give warning. 56 Say: I ask of you no reward for this, save that whoso will may choose a way unto his Lord. 57 Put your trust in the All Living who never dies, and exalt with His praise, He is sufficiently aware of His worshipers' sins. 58 He created the heavens and the earth and all that lies between them in six spans then assumed His authority. He is the benevolent: Ask those who are well-informed. 59 But when they are told, 'Bow yourselves to the All-merciful,' they say, 'And what is the All-merciful? Shall we bow ourselves to what thou biddest us?' And it increases them in aversion. ۩ 60
