Have not those who disbelieve known that the heavens and the earth were of one piece, then We parted them, and we made every living thing of water? Will they not then believe? 30 And We have placed in the earth firm hills lest it quake with them, and We have placed therein ravines as roads that haply they may find their way. 31 We have made the heaven a well-secured canopy; yet still they turn away from Our signs. 32 And He it is Who created the night and the day and the sun and the moon; all (orbs) travel along swiftly in their celestial spheres. 33 We appointed immortality for no mortal before thee. What! if thou diest, can they be immortal! 34 Every soul shall taste death; We test you with both good and evil [circumstances] as a trial. To Us you shall 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 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, 'And when shall the promise come to pass, if you speak truly?' 38 If only those who disbelieved knew (the time) when they will not be able to ward off the Fire from their faces, nor from their backs; and they will not be helped. 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
