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 We have made the heaven a well-secured canopy; yet still they turn away from Our signs. 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 [remind those who deny thee, O Prophet, that] never have We granted life everlasting to any mortal before thee: but do they, perchance, hope that although thou must die, they will live forever?" 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 And when those who disbelieve (in the Oneness of Allah) see you (O Muhammad SAW), they take you not except for mockery (saying): "Is this the one who talks (badly) about your gods?" While they disbelieve at the mention of the Most Beneficent (Allah). [Tafsir. Al-Qurtubi]. 36 The human was created of haste. Indeed, I will show you My signs; so do not ask Me to hasten them. 37 And they say: When will this promise (be fulfilled), if ye are truthful? 38 Had those who disbelieve but known (of the time) when they shall not be able to ward off the fire from their faces nor from their backs, nor shall they be helped. 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 Mocked were (many) messenger before thee; But their scoffers were hemmed in by the thing that they mocked. 41
