Do not those who deny the truth see that the heavens and the earth were joined together and that We then split them asunder? And that We have made every living thing out of water? Will they still not believe? 30 And We placed within the earth firmly set mountains, lest it should shift with them, and We made therein [mountain] passes [as] roads that they might be guided. 31 and We set up the heaven as a roof well-protected; yet still from Our signs they are turning away. 32 And it is He Who created the night and the day, and the sun and the moon; each one floats in an orbit. 33 And before you, We did not appoint on earth a never-ending life for any human; will they, if you depart, become immortal? 34 Every human being is bound to taste death; and We test you [all] through the bad and the good [things of life] by way of trial: and unto Us you all must return. 35 But [thus it is:] whenever they who are bent on denying the truth consider thee, they make thee but a target of their mockery, [saying to one another,] "Is this the one who speaks [so contemptuously] of your gods?" and yet, it is they themselves who, at [every] mention of the Most Gracious, are wont to deny the truth! 36 Man is a creature of haste; [but in time] I shall make obvious to you [the truth of] My messages: do not, then, ask Me to hasten [it]! 37 They say: "When will this promise come to pass, if ye are telling the truth?" 38 If only the disbelievers realised the time when they will not be able to stop the fire from their faces and from their backs – and nor are they to be helped. 39 Nay, it shall come on them all of a sudden and cause them to become confounded, so they shall not have the power to avert 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
