Have you not considered (the work of) your Lord, how He extends the shade? And if He had pleased He would certainly have made it stationary; then We have made the sun an indication of it 45 then We withdrew it to Us, a gradual withdrawal. 46 And He it is Who makes the Night as a Robe for you, and Sleep as Repose, and makes the Day (as it were) a Resurrection. 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 to revive the barren land and provide water for many creatures, cattle, and people. 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 Had We willed, We would have raised up a separate Warner in each habitation. 51 Do not yield to the unbelievers but launch a great campaign against them with the help of the Quran. 52 ۞ And He it is Who has made two seas to flow freely, the one sweet that subdues thirst by its sweetness, and the other salt that burns by its saltness; and between the two He has made a barrier and inviolable obstruction. 53 And He it is who out of this [very] water has created man, and has endowed him with [the consciousness of] descent and marriage-tie: for thy Sustainer is ever infinite in His power. 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 And We have sent thee (O Muhammad) only as a bearer of good tidings and a warner. 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 who created the heavens and the earth and what is between them in six days and then established Himself above the Throne - the Most Merciful, so ask about Him one 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
