Do not those who disbelieve see that the heavens and the earth were closed up, but We have opened them; and We have made of water everything living, will they not then believe? 30 And [are they not aware that] We have set up firm mountains on earth, lest it sway with them, and [that] We have appointed thereon broad paths, so that they might find their way, 31 And We have made the sky a roof, protected; and they turn away from its signs. 32 It is He Who created the Night and the Day, and the sun and the moon: all (the celestial bodies) swim along, each in its rounded course. 33 We have never assigned immortality to a human before you, therefore, if you yourself die, will they live for ever? 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: soon (enough) will I show you My Signs; then ye will not ask Me to hasten them! 37 They say, "When shall the Day of Judgment come to pass if you are true in your claim?" 38 If only the unbelievers knew of the Hour when they shall not be able to keep off the Fire from their faces, nor from their backs; nor shall they be helped. 39 In fact it will suddenly come upon them, therefore shocking them, and they will not be able to repel it nor will they be given respite. 40 Indeed (many) Messengers were mocked before you (O Muhammad SAW), but the scoffers were surrounded by that, whereat they used to mock. 41
