His preaching was for long rejected by the Lamtunas, so on the advice of his patron Yahya, who accompanied him, he retired to an island in the Niger, where he founded a ribat or Moslem monastery, from which as a centre his influence spread.
RABAT (Ribat), a city on the Atlantic coast of Morocco, in 34° 3' N., 6° 46' W., 130 m.
The old town (Medina), the walls of which have in great part disappeared, lies between two suburbs, the Ribat-elSowika on the north and the Ribat Bab-el-Jezira on the south.
Beyond the Jewish quarter, in the Ribat-el-Soweika, is the Place el Halfa-Ouine, a favourite rendezvous of the poorer Moslem population, wherein are many native cafés.
The word is derived from ribat, a fortified frontier station.
