Rabi’ bin Hirash (may Allah have mercy on him) says that when the troublemakers set out towards Hazrat Uthman Ghani (may Allah be pleased with him), I reached Hazrat Hudhaifa bin Yaman (may Allah be pleased with him) in Mada’in. He asked me, “O Rabi’! What happened to your people?” I asked, “What do you want to know about them?” He said, “Who among them has set out towards Hazrat Uthman (may Allah be pleased with him)?” I told him the names of some of them. He said, “I heard the Prophet Muhammad (peace and blessings be upon him) say: Whoever leaves the congregation and humiliates his leader will meet Allah in such a state that he will have no status there.”
