Map 18.2 Tripartite struggle over Kannauj
Al Masudi praised the Balhara rulers or the Rashtrakutas for encouraging Muslim merchants to settle in Konkan, and allowing the practice of their religion. The result was that Al Masudi noted in the early tenth century that Muslim merchants in the Konkan coast were given excellent support by the Rashtrakuta rulers (Balhara kings in the Arab accounts, so named after the Sanskrit term Vallabharaja) are credited with the construction of mosques in the port towns of Konkan.
The Rashtrakutas showed great hospitality to foreigners, and especially to Muslim traders from Arabia and Iran. The latter were permitted to settle in the kingdom's domains; and, according to the Arab traveller, Al-Masudi, nearly 10,000 Muslims lived in the district of Saymur and were known as the bayasiras, or 'Muslims born in Al-Hind of Muslim parents' (Wink 1990: 69).
