10. Muḥammad ibn Ḥasan narrated to me from Muḥammad ibn Ḥasan Al-Saffār, from Aḥmad ibn Muḥammad ibn ‘Isā, from ‘Ali ibn Ḥakam, from Raḥīm, who said: I said to Imam Riďā صلى الله عليه وعلى آله وسلم, “We face some difficulties when we go to the Ziyārah of the grave of Abil Ḥasan (Imam Kāżim عليه السلام) in Baghdad. What are the rewards for those who go to his Ziyārah?” Imam عليه السلام replied, “Its rewards are the same as the rewards for going to (the Ziyārah of) the grave of Ḥusain عليه السلام.” (After Imam عليه السلام said this) a man entered, said Salām to the Imam عليه السلام, and sat down. He started talking about Baghdad and the inferiority of its people and about the afflictions, the collapsing of the earth, the clamour, and the bolts of lightning which are expected to befall Baghdad. Then I got up to leave and I heard Abal Ḥasan (Imam Riďā عليه السلام) say, “As for Abul Ḥasan (Imam Kāżim عليه السلام), none (of this will affect him).”
