Translation of the verse 17 from Surah Al-Muzzammil : Number of verses 20 - - page 574 - Part 29.
Then how can you avoid the punishment, if you disbelieve, on a Day that will make the children grey-headed (i.e. the Day of Resurrection)?
Then how can you fear, if you disbelieve, a Day that will make the children white- haired?
(73:17) If you persist in disbelieving, how will you guard yourself against the (woe of the) Day that will turn children grey-haired, *17
*17) That is, "In the first place, you should be afraid that if you do not accept the invitation of the Messenger sent by Us, you will have to meet the same evil end in this world, which the Pharaoh has already met in consequence of this very crime. But even if no torment is sent on you in the world, how will you save yourselves from the punishment of the Day of Resurrection?"
