A bishop shall not be removed from his bishopric, nor a monk from his monastery, nor a hermit from his tower [sawma‘], nor shall a pilgrim be hindered from his pilgrimage. Moreover, no building from among their churches [bayt min buyut kanaisihim] shall be destroyed, nor shall the money [mal] from their churches be used for the building of mosques or houses for the Muslims. Whoever does such a thing violates Allah’s covenant [ahd Allah] and dissents from the Messenger of Allah.
