"Hakim, son of ‘Awana al Kalbi, succeeded Tamim. The people of India had returned to idolatry excepting those of Kassa, and the Musulmans had no place of security in which they could take refuge, so he built a town on the other side of the lake facing India, and called it Al Mahfuza, “The secure,” and this he made a place of refuge and security for them, and their chief town. He asked the [p. 28] elders of the tribe of Kalb, who were of Syrian descent, what name he should give the town. Some said Dimash [Damascus], others, Hims [Emessa], and others Tadmur [Palmyra]. Hakim said (to the latter), “May God destroy16 you, O fool.” He gave it the name of Al Mahfuza, and dwelt there."
