Like his brother Zaid, Sa'sa bin Sawhaan was also a loyal companion of Hazrat Ali (a.s.). He was a powerful orator. He was also present in the funeral of Ali (a.s.). After the burial of Hazrat Ali (a.s.) he stood up, picking up a handful of dust from the grave he put it on his head and delivered a powerful speech. This was the first Majlis that was held at the grave soon after the burial of Ali (a.s.). The preacher was Sa'sa bin Sawhaan and the audience included great personalities like Imam Hasan (a.s.), Imam Husain (a.s.), Hazrat Abbas (a.s.), Janab Mohammad Hanafiya (a.r.). Everyone was weeping. Janab Sa'sa (r.a.) presented condolence to all the sons. After this Majlis, people returned from Najaf to Kufa. We can understand the greatness of Sa'sa from this incident.
