On Proof of Ar-Ridha’s Rightfulness Due to Predicting that He عليه السلام Would not See Baghdad, And Neither Would Baghdad See Him عليه السلام

49-1 Abu Ali Al-Husayn ibn Ahmad al-Bayhaqi narrated that Muhammad ibn Yahya al-Sowli quoted on the authority of Oun ibn Muhammad, on the authority of Muhammad ibn Abi Abad that one day Al-Ma’mun told Ar-Ridha’ عليه السلام, “When we enter Baghdad, God willing we will do this and that.” Then Ar-Ridha’ عليه السلام told him, “O Commander of the Faithful! You will enter Baghdad.” Abi Abbad added, “When others had left, I heard something which made me feel sad. Then I told the Imam عليه السلام what I had heard. Then Ar-Ridha’ عليه السلام said, ‘O Husayn! What do I have to do with Baghdad? I will never see Baghdad, neither will Baghdad ever see me.’”
