Imam Ridha (AS) replied: To the place where you sent me. Then, Imam (AS) covered his head and came out without saying a word and entered his house and said: Abasalt, close the doors, and Imam (AS) went to his bed to sleep.  

I was worried and standing inside the house when suddenly I saw a very young handsome man with long hair looking like Imam Ridha (AS) who entered the house.

I rushed towards him and asked: The doors were closed, how did you manage to enter the house? The young man replied: The One who has brought me from Medina to here. I asked: Who are you? The young man replied: I am the proof of God to you. O’ Abasalt, I am Mohammad ibn Ali. Then, he went towards his father and entered the room and told me: O’ Abasalt, move aside, there is another person with me who will help me to prepare my father. And then he performed ablution and all necessary cases for the burial of his father, Imam Ridha (AS) [1].
