Narrated to us Muhammad bin Ibrahim bin Ishaq (r.a.): Narrated to us Abu Ahmad Abdullah bin Ahmad bin Muhammad bin Isa: Narrated to us Ali bin Saeed bin Basheer: Narrated to us Ibne Kasib: Narrated to us Abdullah bin Maimoon Makki: Narrated to us Ja’far bin Muhammad from his father from Ali bin Husain in a lengthy tradition at the end of which he said:

“When the Prophet (S) passed away a man came to present his condolences. They could hear him but were not able to see him. He said: “Peace be on you and the mercy of Allah and His bounties. Every living being will taste the taste of death. Your reward will be given fully to you in the Qiyamat. If anyone dies, verily, Allah is his substitute and successor Who provides patience in every calamity and He is the remover of its harm. He compensates every loss. So rely only on Him because the (real) loser is he who loses the reward of Allah.” Ali Ibne Abi Talib said, “Do you know who that is?” “No,” they replied. He said, “It is Khizr .” 

The author says: Most of our opponents accept the traditions about Khizr and they believe that he is alive but he cannot be seen, and that he is present where he is remembered. Neither the opponents deny his long life nor say that these traditions are illogical. However they object to the long life of the Qaim . These people believe that it is within the power of Allah to keep a person alive till the blowing of the horn. They agree to the life and occultation of the accursed Iblees till the known time. But they do not accept the longevity and occultation of the Proof of Allah even though authentic traditions have come down from the Messenger of Allah (S) regarding his name and clarifying about his genealogy and origin.
