Compiled by Imam Abu Dawud as-Sijistani
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عُمَرَ بْنِ مُحَمَّدٍ، عَنْ أَبَانَ بْنِ صَالِحٍ الْقُرَشِيِّ، حَدَّثَنَا عَمْرُو بْنُ مُحَمَّدٍ، - يَعْنِي الْعَنْقَزِيَّ - عَنْ عَبْدِ اللَّهِ بْنِ بُدَيْلٍ، بِإِسْنَادِهِ نَحْوَهُ قَالَ فَبَيْنَمَا هُوَ مُعْتَكِفٌ إِذْ كَبَّرَ النَّاسُ فَقَالَ مَا هَذَا يَا عَبْدَ اللَّهِ قَالَ سَبْىُ هَوَازِنَ أَعْتَقَهُمُ النَّبِيُّ صلى الله عليه وسلم قَالَ وَتِلْكَ الْجَارِيَةُ . فَأَرْسَلَهَا مَعَهُمْ .
The tradition mentioned above (No. 2468) has also been transmitted by Abdullah ibn Budayl through a different chain of narrators in a similar way. This version adds: While he (Umar) was observing i'tikaf (in the sacred mosque), the people uttered (loudly): "Allah is most great." He said: What is this, Abdullah? He said: These are the captives of the Hawazin whom the Messenger of Allah (ﷺ) has set free. He said: This slave-girl too? He sent her along with them.
