9. Muḥammad ibn Ḥasan ibn Aḥmad ibn Walīd narrated to me from Sa’d, from Aḥmad ibn Muḥammad, from Aḥmad ibn ‘Ubdūs Al-Khalanji, from his father Raḥīm, who said: I said to Imam Riďā , “May I sacrifice myself for you! We face some difficulties when we go to the Ziyārah of the grave of Abil Ḥasan (Imam Kāżim ) in Baghdad. Therefore, when we go to his Ziyārah, we say Salām to him from behind the walls. What are the rewards for those who go to his Ziyārah?” Imam replied: I swear to Allāh that it is the same as the rewards for going to (the Ziyārah of) the grave of the Messenger of Allāh ﷺ.
