Malay is spoken as a second language by a minority of the Tausug, Sama-Bajau, and Yakan peoples in the southernmost parts of the Philippines, from Zamboanga down to Tawi-Tawi. It is also spoken as a daily language by the Malaysians and Indonesians who have settled, or do business in the Philippines. It is also spoken in southern Palawan to some extent. It is not spoken among the Maranao and Maguindanao peoples. Brunei, Malaysia, Indonesia and the southern Philippines are largely Islamic and the liturgical language of Islam is Arabic, but the vast majority of Muslims in the Philippines have little practical knowledge of Arabic beyond limited religious terminology.
