It is narrated from Sayyidah Umm Ayman (may Allah be pleased with her) that she said: The Prophet (peace and blessings be upon him) got up at night and urinated in an earthenware vessel (fakhkhar) kept in a corner of the house. Then I got up during the night, very thirsty, and unknowingly drank what was in that vessel. In the morning the Prophet (peace and blessings be upon him) said: "O Umm Ayman! Get up and pour out whatever is in that earthenware vessel." I said: By Allah! I have drunk it. The narrator says: Hearing this, the Messenger of Allah (peace and blessings be upon him) laughed until his (peace and blessings be upon him) molar teeth became visible, then he said: "Know that after this your stomach will never suffer any pain (ache or illness)."

It is narrated from Mus'ab bin Abdullah that Sayyidah Umm Ayman (may Allah be pleased with her), the freed slave-woman and nurse of the Messenger of Allah (peace and blessings be upon him), passed away in the early days of the caliphate of Sayyiduna Uthman bin Affan (may Allah be pleased with him).
