One day in his sermon, Imam Khomeini stated that a person came to see Imam Sadiq – peace be upon him – and said:
“O descendant of the Prophet of Allah I have come to make a request to you that you intercede for me on the Day of Resurrection and mediate that I go to paradise and attain eternal bliss.
In response Imam Jafar Sadiq – peace be upon him – told him that he (Imam Sadiq) would guarantee intercession on his behalf but provided that he was resurrected as (in the form of a ) a human being.”
The Imam then remarked:
“This phrase of Imam Sadiq – peace be on him – breaks a person’s back. Is it or is it not possible for us to be resurrected as (in the form of) human beings (on the Day of Resurrection)?”
