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 Then He reduces it in gradual steps. 46 And it is Allah Who has ordained the night as a garment for you, and the sleep as a repose of death, and the day as the time of return to life. 47 And He it is Who sendeth the winds, glad tidings heralding His mercy, and We send down purifying water from the sky, 48 That We may give life thereby to a dead land, and We give many beasts and men that We have created to drink thereof. 49 We present the same phenomenon over and over again before them so that they may learn a lesson from it; but most people decline to adopt any other attitude than of disbelief and ingratitude. 50 If We willed, We could have sent a Herald of Warning to every village. 51 So obey not the disbelievers, but strive against them herewith with a great endeavour. 52 ۞ It is He Who has let free the two bodies of flowing water: One palatable and sweet, and the other salt and bitter; yet has He made a barrier between them, a partition that is forbidden to be passed. 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 But they worship rather than Allah that which does not benefit them or harm them, and the disbeliever is ever, against his Lord, an assistant [to Satan]. 55 Yet [withal, O Prophet,] We have sent thee only as a herald of glad tidings and a warner. 56 Say: 'I do not ask of you a wage for this, except for him who wishes to take to his Lord a way.' 57 And rely on the Ever-living Who dies not, and celebrate His praise; and Sufficient is He as being aware of the faults of His servants, 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 And when it is said unto them: Prostrate to the Beneficent! they say: And what is the Beneficent? Are we to prostrate to whatever thou (Muhammad) biddest us? And it increaseth aversion in them. ۩ 60
