Have you not seen that your Lord increases the shadow. Had He wanted He would have made it stationary], and has made the sun their guide. 45 Then We withdraw it to Us a gradual concealed withdrawal. 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 sends the winds as heralds of glad tidings, going before His mercy, and We send down pure water from the sky,- 48 so that He may revive the dead land, and quench the thirst of many of His creatures from among beasts and men. 49 And We have certainly distributed it among them that they might be reminded, but most of the people refuse except disbelief. 50 If We had willed, We would have raised up in every city a warner. 51 So do not follow the unbelievers, and strive against them a mighty striving with it. 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 It is He Who has created man from water: then has He established relationships of lineage and marriage: for thy Lord has power (over all things). 54 And they worship such, other than Allah, which neither benefit nor hurt them; and the disbeliever helps the devil instead of his Lord. 55 O Muhammad, We have sent you only to proclaim good tidings and to give warning. 56 Say: I do not ask you aught in return except that he who will, may take the way to 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 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 it is said to them. "Prostrate yourselves before the Merciful," they retort, "What is the Merciful? Would you have us prostrate ourselves before whomsoever you will?" And this invitation only helps to increase their hatred all the more. ۩ 60
