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 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 set up the heaven as a roof well-protected; yet still from Our signs they are turning away. 32 It is He who created the night and the day, the sun and the moon, each swimming in a sky. 33 We appointed immortality for no mortal before thee. What! if thou diest, can they be immortal! 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 was created of haste. I will show you My signs, so do not impatiently urge Me. 37 And they say: "When will this promise (come to pass), if you are truthful." 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 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 Before you, other Messengers were mocked, but the mockers were encompassed by the very thing they mocked. 41
