Sunan Abi Dawud 23523
In-book no 3019حَدَّثَنَا ابْنُ السَّرْحِ، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ بْنُ يَزِيدَ، عَنِ ابْنِ شِهَابٍ، قَالَ بَلَغَنِي أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم افْتَتَحَ خَيْبَرَ عَنْوَةً بَعْدَ الْقِتَالِ وَنَزَلَ مَنْ نَزَلَ مِنْ أَهْلِهَا عَلَى الْجَلاَءِ بَعْدَ الْقِتَالِ .
Ibn Shihab said “It has reached me that the Apostle of Allaah(ﷺ) conquered Khaibar by force. Its inhabitants who came down (from their fortress) for expulsion came down after fighting.”
