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 We placed stabilisers in the earth so that as it revolved with them you lived undisturbed; and We provided passageways between them so that men may find their way; 31 and [that] We have set up the sky as a canopy well-secured? And yet, they stubbornly turn away from [all] the signs of this [creation,] 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 living being must taste death; and We test you with harm and with good – a trial; and to Us only you have to 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. Soon I will show you My signs, but do not ask Me to hasten them. 37 And they say: When will this threat come to pass if you are truthful? 38 Had those who disbelieve but known (of the time) when they shall not be able to ward off the fire from their faces nor from their backs, nor shall they be helped. 39 That will suddenly come upon them and stupefy them. They shall not be able to ward it off, nor shall they be granted any 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
