Barirah was emancipated, and she was the wife of Mughith, a slave of Aal AbuAhmad. The Messenger of Allah ﷺ gave her choice, and said to her: If he has intercourse with you, then there is no choice for you. (Using translation from Abū Dāʾūd 2236)
بَرِيرَةَ أُعْتِقَتْ وَهِيَ عِنْدَ مُغِيثٍ عَبْدٍ لِآلِ أَبِي أَحْمَدَ فَخَيَّرَهَا رَسُولُ اللهِ ﷺ وَقَالَ لَهَا إِنْ قَرِبَكِ فَلَا خِيَارَ لَكِ
