Have the unbelievers not seen that the heavens and the earth were sewn up as one (solid) mass, then We unstitched them, and that We made every living thing of water? Will they not believe! 30 We set firm mountains upon the earth lest it should shake with them, and We placed therein ravines to be paths so that they might be guided. 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 the Night and the Day, and the sun and the moon: all (the celestial bodies) swim along, each in its rounded course. 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 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 The human being is created hasty. Tell them, "Do not be hasty, for God will soon show you the evidence of His existence". 37 And they say, "When is this promise, if you should be truthful?" 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 may come to them all of a sudden and confound them: no power will they have then to avert it, nor will they (then) get respite. 40 Messengers before thee, indeed, were mocked, but that whereat they mocked surrounded those who scoffed at them. 41
