Conquest by treaty (sulh)

الفتح صلحاً

Fath sulhan in al-Baladhuri is taking a town by negotiated capitulation without combat: his first example is Fadak — on his return from Khaybar the Prophet sent Muhayyisa ibn Masud al-Ansari calling its people to Islam, 'and they made peace with the Prophet on half the land with its soil, and he accepted that from them', so its people remained in it through the Prophet's life and Abu Bakr's until Umar exiled them; sulh contrasts with 'anwa — treaty peoples keep their lands and property on the treaty's terms except what was stipulated, and the half-land treaty made half of Fadak pure fay' for the Prophet 'because the Muslims had not charged upon it with horse or camel'.
