A female slave, whose husband is a slave, has the option to keep him or leave him (when she is manumitted).
حَدَّثَنَا عَبْدُ الأَعْلَى بْنُ حَمَّادٍ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا أَيُّوبُ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ ذَاكَ مُغِيثٌ عَبْدُ بَنِي فُلاَنٍ ـ يَعْنِي زَوْجَ بَرِيرَةَ ـ كَأَنِّي أَنْظُرُ إِلَيْهِ يَتْبَعُهَا فِي سِكَكِ الْمَدِينَةِ، يَبْكِي عَلَيْهَا.
Narrated Ibn `Abbas: That was Mughith, the slave of Bani so-and-so, i.e., Barira's husband as if I am now looking at him following her (Barira) along the streets of Medina.
