Mustadrak al-Hakim — Hadith 6673

Ahmad bin Ya'qub transmits this same lineage from his teachers, and added to it that his mother was Sayyidah Umm Ayman (may Allah be pleased with her), the freed slave-woman of the Messenger of Allah (peace and blessings be upon him). He died in Madinah in the last part of the caliphate of Sayyiduna Mu'awiyah (may Allah be pleased with him), when he was sixty years old, and his kunyah was Abu Muhammad.
