Note 332 — Chapter XX · CONQUEST OF PALESTINE. A.H. XV. A.D. 636.
Reading edition
The monks of the ‘Convent of Khâlid,’ near Damascus, received a permanent remission of their land tax as a reward for the treacherous aid rendered by them at the siege of that city. A similar concession was enjoyed by the Samaritans, who hated both Jews and Christians equally, and aided the Arabs as guides and spies; but the fruits of their treachery were resumed by Yezîd.
Omar made an assignment from the tithes to a colony of Christian lepers near Jâbia; but it seems to have been a purely charitable grant.
