Sayyiduna Ali (may Allah be pleased with him) forbade his companions from showing leniency towards the Khawarij. These people passed by Abdullah bin Khabbab, so they seized him and took him along with them. They passed by a date that had fallen from a tree; one of them picked up the date and put it in his mouth. Another person said to him, "You have eaten a date belonging to someone under a pact; on what basis have you made it lawful for yourself?" Abdullah bin Khabbab said, "Shall I not guide you to something that is more worthy of respect for you than this?" The people said, "Yes." Abdullah bin Khabbab said, "I am that (person)." Then those people killed Abdullah bin Khabbab. This news reached Sayyiduna Ali (may Allah be pleased with him), so he sent a message to the people: "You must pay us the blood money for Abdullah bin Khabbab." They replied, "How can we pay you his blood money when each one of us has killed him?" Sayyiduna Ali (may Allah be pleased with him) asked, "Did all of you kill him?" They replied, "Yes." So Sayyiduna Ali (may Allah be pleased with him) said, "Allahu Akbar!" Then he ordered that (his companions) launch a full attack on those people. Sayyiduna Ali (may Allah be pleased with him) said, "By Allah! Not even ten of you will be martyred, and not even ten of them will survive." The narrator states: So Sayyiduna Ali (may Allah be pleased with him) had all those people killed. Sayyiduna Ali (may Allah be pleased with him) ordered, "Look for the one with the protruding flesh among them." After this, the narrator mentioned the entire incident.
