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 [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 made the sky a protected ceiling, but they, from its signs, are turning away. 32 and [fail to see that] it is He who has created the night and the day and the sun and the moon - all of them floating through space! 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 with evil and with good, for ordeal. And unto Us ye 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 And they say: "When will this promise (come to pass), if you are truthful." 38 If the unbelievers only knew when they will be unable to shield either their faces or their backs from the Fire; when they will not be helped! 39 Nay, but it shall come upon them suddenly, dumbfounding them, and they shall not be able to repel it, nor shall they be respited. 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
