3. ‘Ali ibn Ḥusain narrated to me from Muḥammad ibn Yaḥyā Al-‘Aťťār, from Muḥammad ibn Aḥmad, from Hārūn ibn Muslim, from Abī ‘Ali Al-Ḥarrāni, who said: I asked Abā ‘Abdillāh (Imam Sādiq ), “What is the reward for those who go to the Ziyārah of the grave of Ḥusain ?” Imam replied, “Allāh will register the reward of performing a Hajj and an ‘Umrah for those who go to the grave of Ḥusain , perform his Ziyārah, and establish two or four Rak’ah of prayer next to him.” I asked, “May I sacrifice myself for you! Is this (reward) the same for those who go to (the Ziyārah of) the grave of the (other) Imams whose obedience is obligatory?” Imam replied, “The reward is the same for anyone who goes to (the Ziyārah of) the grave of the (other) Imams whose obedience is obligatory.” The above Ḥadīth has also been narrated to me through the following chains: A) Muḥammad ibn Ḥusain ibn Mat Al-Jawhari, from Muḥammad ibn Aḥmad, from Hārūn ibn Muslim, from Abī ‘Ali Al-Ḥarrāni, from Abī ‘Abdillāh . B) My father, from Sa’d ibn ‘Abdillāh, from Abil Qāsim, from Abī ‘Ali Al-Khuzā’i, from Abī ‘Abdillāh .
