فَكَيْفَ تَتَّقُونَ إِن كَفَرْتُمْ يَوْمًا يَجْعَلُ الْوِلْدَانَ شِيبًا (17)
(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?"
