Chapter on Whose Testimony Must Be Rejected and Whose Testimony Must Be Accepted

And Al-Hasan ibn Mahbub narrated from Hisham ibn Salim, from Ammar ibn Marwan, who said: I asked Abu Abdullah عليه السلام, or it is said that one of his companions asked him, regarding a man who testifies in favor of his father, or a brother for his brother, or a man for his wife. Imam عليه السلام said: "There is no harm in that if he is righteous. His testimony is accepted for his father, and a father's testimony is accepted for his son, and a brother's testimony is accepted for his brother."
