2. Abul ‘Abbās Al-Qurashi narrated to me from Muḥammad ibn Ḥusain, from Muḥammad ibn Ismā’īl, from Sāliḥ ibn ‘Uqbah, from Abī Sa’īd Al-Madā`ini, who said: I asked Abā ‘Abdillāh (Imam Sādiq (a.s.)), “May I sacrifice myself for you! Should I go to the grave of the son of the Messenger of Allāh (s.a.a.w.) (Imam Ḥusain (a.s.))?” Imam (a.s.) replied: O Abā Sa’īd! Yes! Go to the grave of the son of the Messenger of Allāh (s.a.a.w.), the most blessed of the blessed ones, the most purified of the purified ones, and the most pious of the pious ones; for if you go to his Ziyārah, Allāh will register the reward of freeing twenty-five slaves for you. The above Ḥadīth has also been narrated to me through the following chain: My father, from a group of our companions, from Sa’d ibn ‘Abdillāh, from Aḥmad ibn Muḥammad ibn ‘Isā, from Muḥammad ibn Ismā’īl, from Sāliḥ ibn ‘Uqbah, from Abī Sa’īd Al-Madā`ini, from Abī ‘Abdillāh (a.s.).
