Have not those who disbelieve known that the heavens and the earth were joined together as one united piece, then We parted them? And We have made from water every living thing. 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 And We made the sky a well-protected roof. Still they turn away from His 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 And We did not grant to any man before you eternity [on earth]; so if you die - would they be eternal? 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 When the unbelievers see you they make you an object of fun, saying: "Is he the one who mentions your gods?" They say so, and yet they reject with disdain the very mention of the Most Compassionate Lord. 36 The human was created of haste. Indeed, I will show you My signs; so do not ask Me to hasten them. 37 Yet they say: "When will the promised threat come to pass, if you speak the truth?" 38 If those who disbelieved but knew the time when they will not avert the Fire from their faces or from their backs and they will not be aided... 39 It will overtake them suddenly, dumbfounding them. They shall be unable to ward it off, and they shall not 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
