1. My father, ‘Ali ibn Ḥusain, and Muḥammad ibn Ya’qūb all narrated to me from ‘Ali ibn Ibrāhīm ibn Hāshim, from his father, from Aḥmad ibn Muḥammad ibn Abī Nasr, who said: Some of our companions asked Abal Ḥasan (Imam Riďā ) about (the reward of) those who go to (the Ziyārah of) the grave of Ḥusain . Imam replied, “It is equal to performing an ‘Umrah.”
