The Messenger of Allah صلى الله عليه وسلم said: “There are four who will be tested on the Day of Resurrection: the deaf who could not hear anything; the imbecile; the senile old man; and the man who died during the fatarah (interval between two Prophets, when no Message reached him).
The deaf man will say, “O Lord, Islam came and I did not hear anything.”The imbecile will say, “O Lord, Islam came but the young boys were pelting me with camel dung.” The senile old man will say, “O Lord, Islam came and I did not hear anything.” The man who died during the fatarah will say, “O Lord, no Messenger came to me.”
Then Allah will take their pledge to obey Him, and He will send word to them to enter the fire. By the One in Whose hand is the soul of Muhammad, if they enter it, it will be cool and safe for them.”
