Do not those who disbelieve see that the heavens and the earth were closed up, but We have opened them; and We have made of water everything living, will they not then believe? 30 And We placed firm mountains on earth lest it should sway with them, and We made wide paths in them that they may find their way; 31 And We made the sky a well-protected roof. Still they turn away from His signs! 32 And it is He Who created the night and the day, and the sun and the moon; each one floats in an orbit. 33 We have not granted everlasting life to any human being before you; then if you [Muhammad] should die, will they live forever? 34 Every soul is going to taste of death, and We shall prove you with evil and good as a temptation; and unto Us ye shall be returned. 35 When the unbelievers see you, they take you only for mockery, saying: 'Is this he who talks about your gods' While they are unbelievers in the Remembrance of the Merciful. 36 Man was created of haste, surely I shall show you My signs, so ask Me not to hasten. 37 But they [who reject My messages are wont to] ask, "When is that promise [of God's judgment] to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!" 38 If only those who deny the truth knew the time when they would not be able to ward off the fire neither from their faces nor from their backs. They will not be helped! 39 Nay, but [the Last Hour] will come upon them of a sudden, and will stupefy them: and they will be unable to avert it, and neither wilt they be allowed any respite. 40 Messengers indeed were mocked at before thee, but those that scoffed at them were encompassed by that they mocked at. 41
