Hadith.5515 - Al-Hasan ibn Ali Al-Washa' narrated from Muhammad ibn Yahya from the executor of Ali ibn Al-Sari, who said: I said to Abu Al-Hasan عليه السلام: "Ali ibn Al-Sari has passed away and appointed me as his executor." Imam عليه السلام said: "May Allah سبحانه وتعالى have mercy on him." I said: "His son Ja'far committed an act with his father's umm walad (concubine), and he instructed me to exclude him from the inheritance." Imam عليه السلام said: "Exclude him if you are truthful, and he will suffer affliction." He (the executor) said: I returned, and Ja'far brought me before Abu Yusuf the judge. Ja'far said to him, "May Allah سبحانه وتعالى rectify your affairs. I am Ja'far, the son of Ali ibn Al-Sari, and this is my father's executor. Order him to give me my inheritance from my father." The judge asked me: "What do you say?" I replied: "Yes, this is Ja'far, the son of Ali ibn Al-Sari, and I am his executor." The judge said: "Then hand over his wealth to him." I said: "I wish to speak with you." He (the judge) said: "Come closer." I approached him so that no one could hear me, and I said: "This man committed an act with his father's umm walad, and his father commanded me in his will to exclude him from the inheritance and not give him anything. I went to Imam Musa ibn Jafar Al-Kadhim عليه السلام, in Medina, informed him, and sought his guidance. Imam عليه السلام ordered me to exclude him from the inheritance and not give him anything." The judge said: "By Allah سبحانه وتعالى, did Abu Al-Hasan command you to do this?" I said: "Yes." He (the judge) made me swear three times and then said: "Carry out what you were ordered. His عليه السلام word is decisive." The executor said: After that, Ja'far was afflicted with madness. Abu Muhammad Al-Hasan ibn Ali Al-Washa' said: I saw him after that.
