4. My father narrated to me from Sa’d, from Aḥmad ibn Muḥammad ibn ‘Isā, from ‘Abbās ibn Mūsā Al-Warrāq, from Yūnus, from ‘Isā ibn Sulaymān, from Muḥammad ibn Ziyād, from his aunt, who said: I heard Abā ‘Abdillāh (Imam Sādiq ) say: Verily the clay of the Ḥā`ir, where Ḥusain is buried, is the cure for every disease and it is protection against any fear.
