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 And We placed firm mountains on earth lest it should sway with them, and We made wide paths in them that they may find their way; 31 and We made the sky a secure canopy; and yet they turn away from these Signs. 32 It is He who created the night and the day, the sun and the moon, each swimming in a sky. 33 We have not granted everlasting life to any human being before you; then if you [Muhammad] should die, will they live forever? 34 Every soul will taste death. And We test you with evil and with good as trial; and to Us you will be returned. 35 (Muhammad), whenever the unbelievers see you, they think that you deserve nothing more than to be mocked. They say, "Is it he, (Muhammad), who speaks against your gods?" But they themselves have no faith at all in the Beneficent God. 36 Man is hasty by nature. I shall certainly show you My Signs. Do not ask Me to be hasty. 37 They say: "(Tell us) when will the threat of punishment 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 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 already were messengers ridiculed before you, but those who mocked them were enveloped by what they used to ridicule. 41
