11. Muḥammad ibn Ja’far Al-Razzāz narrated to me from Muḥammad ibn Ḥusain, from Hajjāl, from Safwān ibn Mihrān, who said: I asked Abā ‘Abdillāh (Imam Sādiq ) about the location of the grave of the Commander of the Believers . He described that it was located in the land of the hardened sands. I went to the described location and established prayers there. The following year, I went back to the Imam and informed him that I had gone to the described location and had prayed there. He told me that I had found the correct location. For twenty years thereafter, I used to go to that described location every year and establish prayers next to it.
