Abu Qilabah (may Allah have mercy on him) narrates that a man from Quraysh called Thumamah was the governor of San'a'. When Sayyiduna Uthman (may Allah be pleased with him) was martyred, he delivered a sermon and wept bitterly. When he recovered and composed himself, he said: "Today the caliphate of prophethood has been taken away from the Ummah of Muhammad (peace and blessings be upon him), and it has become kingship and tyranny; whoever takes something will become its owner."
