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 withdraw it unto 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 sends the winds as heralds of glad tidings, going before His Mercy (rain), and We send down pure water from the sky, 48 That with it We may give life to a dead land, and slake the thirst of things We have created,- cattle and men in great numbers. 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 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 disbelievers, and strive against them with the Qur'an a great striving. 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 it is He Who created man from water, then appointed relatives and in-laws for him; and your Lord is All Able. 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 sent thee but as a bearer of glad tidings and 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 Put thy trust in the Living God, the Undying, and proclaim His praise. Sufficiently is He aware of His servants 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 to (Allah) Most Gracious!", they say, "And what is (Allah) Most Gracious? Shall we prostrate to that which thou commandest us?" And it increases their flight (from the Truth). ۩ 60
