ARE, THEN, they who are bent on denying the truth not aware that the heavens and the earth were [once] one single entity, which We then parted asunder? and [that] We made out of water every living thing? Will they not, then, [begin to] believe? 30 And We have placed on the earth firm mountains, lest it should shake with them, and We placed therein broad highways for them to pass through, that they may be guided. 31 We made the sky above them as a well-guarded ceiling, but they have neglected the evidence (of Our existence) therein. 32 And He it is Who has created the night and the day, and the sun and the moon, each in an orbit floating. 33 And We appointed not for any human being before thee immortality; if thou then diest, are they to be immortals? 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, 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 the unbelievers only knew when they will be unable to shield either their faces or their backs from the Fire; when they will not 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 They mocked the Messengers who were sent before you; thus, the torment which they had ridiculed encompassed them all. 41
