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 We hold it in hand for a brief grasp. 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 He it is Who sendeth the winds, glad tidings heralding His mercy, and We send down purifying water from the sky, 48 so that We may bring life to a dead land; and slake the thirst of Our creation; cattle and men, in great numbers. 49 And We distribute it among them in various ways that they may ponder and reflect; yet most men disdain everything but denial and thanklessness. 50 Now had We so willed, We could have [continued as before and] raised up a [separate] warner in every single community: 51 So do not obey the unbelievers, but struggle mightily with it (the Koran). 52 ۞ AND HE it is who has given freedom of movement to the two great bodies of water - the one sweet and thirst-allaying, and the other salty and bitter - and yet has wrought between them a barrier and a forbidding ban. 53 And He it is Who hath created man from water, and hath appointed for him kindred by blood and kindred by marriage; for thy Lord is ever Powerful. 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 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 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 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
