Section on Ṣafiyyah:
Al-Bakkāʾī related, on the authority of Ibn Isḥāq: The Messenger of Allah ﷺ drew near to the estates, taking them parcel by parcel and conquering the strongholds one after another. The first of their fortresses he opened was the fortress of Nāʿim, during whose assault Maḥmūd ibn Maslama al-Anṣārī—the brother of Muḥammad—was killed when a millstone was hurled down upon him.

Once they had accepted those terms, they asked the Messenger of Allah ﷺ to let them cultivate the lands for half of the yield, whereupon he said, “We are better acquainted with them than you and can maintain them longer.” He therefore concluded a settlement with them for half the produce, stipulating: “If at any time we choose to expel you, we will expel you.” The people of Fadak made peace with him on the same terms. Thus the estates of Khaybar became fayʾ (public booty) shared among the Muslims, whereas Fadak was reserved exclusively for the Messenger of Allah ﷺ, because
