It is narrated from Imam al-Hasan al-Basri that he said: "Sixteen men from the household of Husayn bin Ali (may Allah be pleased with him) were martyred along with him. By Allah! On that day there was no household on the face of the earth like them." Sufyan (bin Uyaynah) said: "Who could doubt this?"
