15. Ali ibn Muhammad has narrated from Muhammad ibn Salih who has said the following. “When my father died and the task (of working is representative of the Imams) was left to me with my father there were promissory notes from those who has said the following. owed (religious dues). I wrote to him (the Imam عليه السلام about the case. He wrote back to me, “Demand from them and make them pay.” People paid what they owed except one man who had signed a promissory note for four hundred Dinars. I went to demand from him what he owed but he procrastinated and took it lightly and his behaved foolishly. I complained to his father and he said, “So what!” I then hold him by his beard and leg and pulled him towards the center of the house and kicked him many times. His son went out and cried for help from the people of Baghdad saying, “He is a Qummi, Rafidi (derogatory name for Shi‘a) he has killed my father.” From the people of Baghdad many gathered around me. I rode my equine animal and said, “Very nice of you people of Baghdad. You support the unjust against a lonely stranger. I am a man from the sunni sect and he calls me a man from Qumm and a Rafidi so that he can destroy my rights.” The narrator has said that people then turned against him and they wanted to enter his store. I then calmed them down. The signatory in the promissory note called me and set upon himself a stipulation with an oath that said, “His wife will be divorced if he did not pay his dues.” My part of the stipulation was to ask the people to leave his place.”
