Sunan at-Tirmithiy كتاب الرضاع باب ما جاء فى المرأة تعتق ولها زوج
Barīrah's husband was a bondsman [at the time she was freed], so the Messenger of God, peace and blessings of God be upon him, gave her the choice [to either remain with him or be separated]. She opted to be single. Had he been a free man, he would not have given her that choice.
