It is narrated from Hasan, he says: Sayyiduna Ali (may Allah be pleased with him) summoned Muhammad bin Maslamah. When he was brought, Sayyiduna Ali (may Allah be pleased with him) said to him: Why have you stayed back from this battle? He replied: Your cousin, that is, the Noble Prophet (peace and blessings be upon him), granted me a sword and said: As long as there is fighting against the enemies of Islam, continue to fight with this sword, and when you see that people, meaning Muslims, are fighting among themselves and shedding each other's blood, then strike it on a stone and break it, and then remain inside your house until death comes to you or the hand of an oppressor reaches you. Sayyiduna Ali (may Allah be pleased with him) said: Leave him.
