134. A number of our companions, from Sahl Bin Ziyad, from Muammar Bin Khallaad who said: Abu Al-Hassan Al-Ridha said to me: ‘Al-Ma’moun said to me , ‘O Abu Al-Hassan , if you could write to some of the ones who are obedient to you in these areas in which their relationship with us is spoilt’. I said to him: ‘O Chief of believers, if you fulfil (your commitment) to me , I would (fulfil my commitment) to you, but rather, I have entered into this matter in which I have been entered into, I do not issue commands, nor do I prohibit, nor do I appoint anyone, nor do I dismiss anyone, and this matter which I have entered into has not increased anything for me regarding the favours. And I used to be in Al-Medina, and my letter would be established in the east and the west, and I would ride upon my mule and pass by in the markets of Al-Medina, and there would be no one more prestigious than me , and there was none among them who would question me for a need with the possibility of my fulfilling it, except that I would fulfill it for him’. He said, ‘I will fulfill (my commitment) to you ’.
