Abu Bakr bin Abi al-Jahm narrates: Yazid bin Hasan and I came along, with Rummanah, the slave of Abd al-Aziz bin Marwan, between us. We had raised our hands and he was leaning on them. He entered the mosque, that is, he entered the mosque of the Prophet (peace and blessings be upon him). There, a Companion of the Prophet (peace and blessings be upon him), Sayyiduna Ibn Niyar (may Allah be pleased with him), was present. He sent a message to Abu Bakr: Come to me. He came to him, and he said: I saw Ibn Rummanah walking between you, leaning on you, between you and Zayd bin Hasan; and I heard the Prophet (peace and blessings be upon him) say: "The world will not come to an end until it comes into the hands of a fool, son of a fool."
