On The Reasons why Ali ibn Musa Ar-Ridha عليه السلام accepted the succession to the throne from Al-Ma’mun, what Went On, those who were displeased and those who were pleased

40-24 Al-Hakim Abu Ali Al-Husayn ibn Ahmad al-Bayhaqi narrated that Muhammad ibn Yahya al-Sowli quoted on the authority of Muhammad al-Kendi, on the authority of Abul Husayn Muhammad ibn Abi Abbad, “When the case of Al-Fadhl ibn Sahl reached the point at which he was killed, Al-Ma’mun went to see Ar-Ridha’ عليه السلام crying and told him, “O Abal Hassan (Ar-Ridha’ عليه السلام)! This is the time in which I need you. Please take charge of the affairs and help me.” The Imam عليه السلام said, “O Commander of the Faithful (Al-Ma’mun)! You are in charge of running the affairs, and I am in charge of praying.” When Al-Ma’mun left, I (Abul Husayn) asked Ar-Ridha’ عليه السلام, “May God honor you! Why didn’t you accept what he offered?” He عليه السلام replied, “O Aba Husayn! Woe be to you! Are you not at all affected by what has happened?” When the Imam عليه السلام noticed that I was upset about what had happened, he عليه السلام said, “Why are you thinking about this issue? If things happen the way that you think they should, and your position relative to me be the same as it is now, then your salary will be the same as it is now. You will be the same as other people who are near me.”
