Have you not considered your Lord - how He extends the shadow, and if He willed, He could have made it stationary? Then We made the sun for it an indication. 45 We then gradually withdraw it towards Us. 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 it is He Who sent the winds giving glad tidings before His mercy; and We sent 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 verily We have repeated it among them that they may remember, but most of mankind begrudge aught save ingratitude. 50 Had it been Our Will, We could have sent a warner to every centre of population. 51 Therefore listen not to the Unbelievers, but strive against them with the utmost strenuousness, with the (Qur'an). 52 ۞ It is He who made two bodies of water flow side by side, one fresh (and) sweet, the other brine (and) bitter, and has placed an interstice, a barrier between them. 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 Yet they worship besides God that which can neither benefit them nor harm them. One who denies the truth is a helper [of evil] against his Lord. 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 for it any payment - only that whoever wills might 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 Who created the heavens and the earth and what is between them in six periods, and He is firmly established on the throne of authority; the Beneficent Allah, so ask respecting it one aware. 59 And when it is said unto them: prostrate yourselves unto the Compassionate, they say: and what is the Compassionate? Shall we prostrate ourselves unto that which thou commandest us? And it increaseth in them aversion. ۩ 60
