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 set on the earth mountains standing firm, lest it should shake with them, and We have made therein broad highways (between mountains) for them to pass through: that they may receive Guidance. 31 And we have made the sky a roof withheld (from them). Yet they turn away from its portents. 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 granted not to any human being immortality before you (O Muhammad SAW), then if you die, would they 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 Man is a creature of haste; [but in time] I shall make obvious to you [the truth of] My messages: do not, then, ask Me to hasten [it]! 37 They say: 'If you are truthful, when will this promise come' 38 If only the unbelievers could apprehend the moment when they would neither be able to ward off the fire from their faces and their backs, nor help reach them! 39 Indeed, it will come upon them suddenly and confound them; and they will not be able to ward it off, nor shall they be reprieved. 40 And certainly apostles before you were scoffed at, then there befell those of them who scoffed that at which they had scoffed. 41
