Hazrat Ali (may Allah be pleased with him) Al-Azdi narrates that Hazrat Ibn Umar (may Allah be pleased with them both) performed the sacrifice and had his head shaved. I heard him saying to those shaving heads, "Shave up to the two bones." Hazrat Ibn Jurayj says that I asked Hazrat Ata, "Did you yourself hear him saying this to those shaving heads?" He replied, "I have heard people mentioning this, but I have not heard it from him myself."
