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 We placed stabilisers in the earth so that as it revolved with them you lived undisturbed; and We provided passageways between them so that men may find their way; 31 And we have made the sky a roof withheld (from them). Yet they turn away from its portents. 32 It is He who created night and day, the sun and the moon, revolving on its orbit. 33 And before you, We did not appoint on earth a never-ending life for any human; will they, if you depart, become immortal? 34 Every soul must taste of death, and We try you with evil and with good, for ordeal. And unto Us ye will be returned. 35 And when those who disbelieve behold thee they only take thee up for mockery: is this he who mentioneth your gods? while in the mention of the compassionate they are themselves blasphemers. 36 Man is a creature of haste. Soon I will show you My signs, but do not ask Me to hasten them. 37 They say, 'And when shall the promise come to pass, if you speak truly?' 38 If they but knew - they who are bent on denying the truth - [that there will come] a time when they will not be able to ward off the fire from their faces, nor from their backs, and will not find any succour! 39 Nay, it shall come on them all of a sudden and cause them to become confounded, so they shall not have the power to avert it, nor shall they be respited. 40 Before you, other Messengers were mocked, but the mockers were encompassed by the very thing they mocked. 41
