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.
ذَاكَ مُغِيثٌ عَبْدُ بَنِي فُلاَنٍ يَعْنِي زَوْجَ بَرِيرَةَ كَأَنِّي أَنْظُرُ إِلَيْهِ يَتْبَعُهَا فِي سِكَكِ الْمَدِينَةِ يَبْكِي عَلَيْهَا
Barira's husband was a black slave called Mughith, the slave of Bani so-and-so-- as if I am seeing him now, walking behind her along the streets of Medina.
يُقَالُ لَهُ مُغِيثٌ عَبْدًا لِبَنِي فُلاَنٍ كَأَنِّي أَنْظُرُ إِلَيْهِ يَطُوفُ وَرَاءَهَا فِي سِكَكِ الْمَدِينَةِ
[Machine] "The husband of Barira was a slave to a group of people called Al-Ansar, known as Mughith. By Allah, it is as if I can see him now, following her in the streets of Medina, while he is crying."
«أَنَّ زَوْجَ بَرِيرَةَ كَانَ عَبْدًا لِبَنِي فُلَانٍ نَاسٍ مِنَ الْأَنْصَارِ يُقَالُ لَهُ مُغِيثٌ وَاللهِ لَكَأَنِّي أَنْظُرُ إِلَيْهِ الآنَ يَتْبَعُهَا فِي سِكَكِ الْمَدِينَةِ وَهُوَ يَبْكِي»
[Machine] That is a helper, a servant, for the people of such-and-such a tribe, as if I am looking at him, he follows her in the streets of the city, crying over her, meaning Barira.
ذَاكَ مُغِيثٌ عَبْدٌ لِبَنِي فُلَانٍ كَأَنِّي أَنْظُرُ إِلَيْهِ يَتْبَعُهَا فِي سِكَكِ الْمَدِينَةِ يَبْكِي عَلَيْهَا يَعْنِي بَرِيرَةَ
