I said to Abu Al-Hassan Al-Ridha (asws), during the days of Haroun, ‘You (asws) have famed yourself (asws) by this Command, and are sitting in the seat of your (asws) father, whilst the sword of Haroun drips blood’. So he (asws) said: ‘What encouraged me (asws) was what the Rasool Allah (saww) said; ‘If Abu Jahl (la) can take a single hair from my (saww) head (to hurt me (saww)), so testify that I (saww) am not a Prophet (saww), and I (asws) say to you that if Haroun can take a single hair from my (asws) head, so testify that I (asws) am not an Imam (asws)’.
