Musannaf Ibn Abi Shayba 13:1560

Abu Bakr narrated to us, he said: Ghundar narrated to us, from Hisham al-Dastawa'i, from Abu al-Zubayr, from 'Abd Allah ibn Abi Mulaykah: That a woman from the people of 'A'ishah emancipated a slave, so she asked 'A'ishah. She said: "If you emancipated him and did not stipulate his wealth, then his wealth is for him."
