5. My father, ‘Ali ibn Ḥusain, and Muḥammad ibn Ḥasan all narrated to me from Sa’d ibn ‘Abdillāh, from Ya’qūb ibn Yazīd, from Ḥusain ibn Yasār Al-Wāsiťi, who said: I asked Abal Ḥasan (Imam Riďā ), “What are the rewards for those who go to the Ziyārah of the grave of your father (Imam Kāżim ) – may Allāh’s blessings be upon him?” Imam replied, “Go to his Ziyārah!” I asked, “What are its merits?” Imam replied, “Its merits are the same as the merits for those who go to the Ziyārah of his father – referring to the Messenger of Allāh ﷺ.” I asked, “What if I was in fear and could not enter (next to the grave)?” Imam replied, “(Then) say Salām from behind the walls.”
