“I asked abu Ja‘far (a.s.) about the words of Allah, the Most Holy, the Most High, “Satan would try to tamper with the desires of every Prophet or Messenger or Muhaddith (Muhaddith is a commentary of Imam (a.s.), whom We sent . .’” (22:52). I said, ““May Allah take my soul in service for your cause, the word Muhaddith does not exist in our reading. What then is the meaning of The Messenger, Prophet and Muhaddith?” The Imam (a.s.) said, “A messenger is one to whom the angel comes openly and speaks to him. A prophet is one who sees in his dream. Sometimes prophethood and messengership may exist in one person. Al-Muhaddith is one who hears the voice but does not see the person (of the angel).” I then asked, may Allah keep you well, “How would one know that what one sees in his dream is true and that it is from the angel?” The Imam (a.s.) said, “He receives help for success to know the angel. Allah has your book the last book and your Prophet the last of prophets.”
