11. Muḥammad ibn Ḥasan ibn ‘Ali narrated to me from his father, from his grandfather ‘Ali ibn Mahziyār, from Abil Qāsim, from Qāsim ibn Muḥammad, from Isḥāq ibn Ibrāhīm, from Hārūn ibn Khārijah, who said
I asked Abā ‘Abdillah (Imam Sādiq (a.s.)), “May I sacrifice my father and mother for you! It is narrated from your father (a.s.) that (going to the Ziyārah of Ḥusain (a.s.)) is equal to Hajj?!” Imam (a.s.) replied, “Yes. A Hajj and an ‘Umrah, and another Hajj and ‘Umrah…” Hārūn added that the Imam (a.s.) counted ten Hajj and ten ‘Umrah.
