Do not those who disbelieve see that the heavens and the earth were closed up, but We have opened them; and We have made of water everything living, will they not then believe? 30 We set firm mountains upon the earth lest it should shake with them, and We placed therein ravines to be paths so 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 It is He who created night and day, the sun and the moon, revolving on its orbit. 33 (O Muhammad), We did not grant everlasting life to any human being even before you. If you were to die, will they live for ever? 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 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 hasty by nature. I shall certainly show you My Signs. Do not ask Me to be hasty. 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 It will overtake them suddenly, dumbfounding them. They shall be unable to ward it off, and they shall not be respited. 40 And already were messengers ridiculed before you, but those who mocked them were enveloped by what they used to ridicule. 41
