(19) باب فِي صَفَايَا رَسُولِ اللَّهِ صلى الله عليه وسلم مِنَ الأَمْوَالِ
Al-Zuhri, explaining the verse "For this you made no expedition with either cavalry or camelry" said:
The Prophet (ﷺ) concluded the treaty of peace with the people of Fadak and townships which he named which I could not remember ; he blockaded some other people who sent a message to him for capitulation. He said: "For this you made no expedition with either cavalry or camelry" means without fighting. Al-Zuhri said: The Banu al-Nadir property was exclusively kept for the Prophet (ﷺ) ; they did not conquer it by fighting, but conquered it by capitulation. To Prophet (ﷺ) divided it among the Emigrants. He did not give anything to the Helpers except two men were needy.
