4. My father and Muĥammad ibn Ĥasan both narrated to me from Sa’d ibn ‘Abdillāh, from Aĥmad and ‘Abdillāh sons of Muĥammad ibn ‘Isā, from Mūsā ibn Qāsim, from Ĥasan ibn Jahm, who said: I asked Abal Ĥasan (Imam Riďā ), “What do you say about (the reward for) going to the Ziyārah of the grave of Ĥusain ?” Imam  replied, “What is your opinion about this (matter)?” I said, “Some people say that it is equal to performing one Hajj while others say it is equal to performing an ‘Umrah.” Imam  said, “It is equal to performing an accepted ‘Umrah.”
