1. My father narrated to me from Sa’d ibn ‘Abdillāh, from Ya’qūb ibn Yazīd, from Ḥasan ibn ‘Ali, from Yūnus ibn Rafī’ (Rabī’), who said: Abū ‘Abdillāh (Imam Sādiq ) said, “There is some red dust next to the head of Ḥusain ibn ‘Ali which is the cure for every disease except death.” After we heard this Ḥadīth, we went to the Grave (of Ḥusain ) and started digging (the area) next to the head of the grave. After digging an ell, about one dirham of red dust which looked like sand started to flow down from the direction of the head. We took it to Kūfah, mixed it (with water), and covered it. Then we started distributing it to people to cure their diseases.
