Have the unbelievers not ever considered that the heavens and the earth were one piece and that We tore them apart from one another. From water We have created all living things. Will they then have no faith? 30 And We placed within the earth firmly set mountains, lest it should shift with them, and We made therein [mountain] passes [as] roads that they might be guided. 31 And We have made the heaven a guarded canopy and (yet) they turn aside from its signs. 32 and [fail to see that] it is He who has created the night and the day and the sun and the moon - all of them floating through space! 33 We have given no man everlastingness before you. So then if you die, will they live ever after? 34 Every human being is bound to taste death; and We test you [all] through the bad and the good [things of life] by way of trial: and unto Us you all must return. 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 Man was created of haste. Assuredly I shall show you My signs; so demand not that I make haste. 37 And they say, “When will this promise occur, if you are truthful? 38 If only the Unbelievers knew (the time) when they will not be able to ward off the fire from their faces, nor yet from their backs, and (when) no help can reach them! 39 Nay, but it shall come upon them suddenly, dumbfounding them, and they shall not be able to repel it, nor shall they be respited. 40 Messengers indeed were mocked at before thee, but those that scoffed at them were encompassed by that they mocked at. 41
