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 عليه السلام), “What are the rewards for those who go to the Ziyārah of the grave of your father (Imam Kāżim عليه السلام) – may Allāh’s blessings be upon him?” Imam عليه السلام replied, “Go to his Ziyārah!” I asked, “What are its merits?” Imam عليه السلام 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 صلى الله عليه وعلى آله وسلم.” I asked, “What if I was in fear and could not enter (next to the grave)?” Imam عليه السلام replied, “(Then) say Salām from behind the walls.”
