It is narrated from Mujammi' (may Allah have mercy on him) that "Sayyiduna Ali (may Allah be pleased with him) would himself sweep the public treasury (bayt al-mal); then two men would pray in that place, bearing witness that he had not held back the Muslims' wealth in it (without distributing it)."
Imam Musaddad (may Allah have mercy on him) said that Yahya narrated it to us, from Abu Hayyan, from Mujammi'.
