It is narrated from Hazrat Aisha (may Allah be pleased with her) that she had vowed to free a slave from among the descendants of Ismail. During this time, some captives from the Yemeni tribe of Khawlan arrived. Hazrat Aisha (may Allah be pleased with her) wished to free one of the slaves from among them, but the Prophet (peace and blessings be upon him) stopped her. Then, when captives from the tribe of Banu Anbar of Mudar arrived, the Prophet (peace and blessings be upon him) instructed her to free one from among them.
