Abu Nazr reports: When Sayyiduna Uthman bin Maz'oon (may Allah be pleased with him) was buried, Umm al-Ala said: O Abu Sa’ib! You have made your abode in Paradise. When the Prophet (peace and blessings of Allah be upon him) heard her say this, he said: Who is this woman? She replied: O Messenger of Allah! It is I. The Prophet (peace and blessings of Allah be upon him) asked: What do you mean? She said: O Messenger of Allah! (I mean) Sayyiduna Uthman bin Maz'oon (may Allah be pleased with him). The Prophet (peace and blessings of Allah be upon him) said: Yes, Uthman bin Maz'oon, we know only good about him, but I am the Messenger of Allah, yet by Allah! I do not know what will be done with me.
Amr says that the narrator named Abu Nasr heard this narration from Kharijah bin Zaid, from his father.
