Have not those who disbelieve known that the heavens and the earth were of one piece, then We parted them, and we made every living thing of water? 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 have made the sky a roof, protected; and they turn away from its signs. 32 And He it is Who created the night and the day and the sun and the moon; all (orbs) travel along swiftly in their celestial spheres. 33 We have never assigned immortality to a human before you, therefore, if you yourself die, will they live for ever? 34 Every soul must taste of death and We try you by evil and good by way of probation; and to Us you shall be brought back. 35 When the Unbelievers see thee, they treat thee not except with ridicule. "Is this," (they say), "the one who talks of your gods?" and they blaspheme at the mention of (Allah) Most Gracious! 36 Man was created of haste, surely I shall show you My signs, so ask Me not to hasten. 37 And they say: When will this threat come to pass if you are truthful? 38 If those who disbelieved but knew the time when they will not avert the Fire from their faces or from their backs and they will not be aided... 39 Nay, but it will come upon them unawares so that it will stupefy them, and they will be unable to repel it, neither will they be reprieved. 40 Indeed (many) Messengers were mocked before you (O Muhammad SAW), but the scoffers were surrounded by that, whereat they used to mock. 41
