“Once ‘Umar ibn yazid came to me and said, “Ride with us and rode with them and went until we came to the house of Hafs al-Kunasi. He took him also with us and we continued the journey until we arrived at al-Ghari and to the grave. He said, “dismount, this is the grave of Amir al-Mu’minin Ali (a.s.).” We asked him, “How did you find out?” He said, “I have come here several times with abu ‘Abdallah (a.s.) when he was in al-Hira and he told me that this is his (Amir al-Mu’minin Ali (a.s.) grave.”
