Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not 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 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 given no man everlastingness before you. So then if you die, will they live ever after? 34 Everyone is going to taste death, and We shall make a trial of you with evil and with good, and to Us you will be returned. 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. Assuredly I shall show you My signs; so demand not that I make haste. 37 Yet they say: "When will the promised threat come to pass, if you speak the truth?" 38 If the unbelievers but knew when that they shall not ward off the Fire from their faces nor from their backs, neither shall they be helped! 39 Nay, it (the Fire or the Day of Resurrection) will come upon them all of a sudden and will perplex them, and they will have no power to avert it, nor will they get respite. 40 And indeed, [O Muhammad, even] before thy time have [God's] apostles been derided - but those who scoffed at them were [in the end] overwhelmed by the very thing which they had been wont to deride. 41
