Sa’id bin Al Musayyab said “The Apostle of Allaah ﷺ conquered a portion of Khaibar by force.” Abu Dawud said “This tradition was read out to Al Harith bin Miskin while I was a witness”. Ibn Wahb said “Malik told me on the authority of Ibn Shihab, Khaibar was captured by force in part and by peace in part. Most of Al Kutaibah was captured by force and a portion by peace.” I asked Malik “What is Al Kutaibah?” He replied “The land of Khaibar. It had forty thousand palm trees.” (Using translation from Abū Dāʾūd 3017)
أَخْبَرَهُ أَنَّ رَسُولَ اللهِ ﷺ افْتَتَحَ بَعْضَ خَيْبَرَ عَنْوَةً
