Arab and Somali Muslim immigrants were few in total number compared to the Indonesians and Bantus, but they left a lasting impression. The Malagasy names for seasons, months, days, and coins are Islamic in origin, as is the practice of circumcision, the communal grain pool, and different forms of salutation. The Arab magicians, known as the ombiasy, established themselves in the courts of many Malagasy tribal kingdoms. The Arab-Somali immigrants brought their patriarchal system of family and clan of non-Islamic civilization rule to Madagascar, which differed from the Polynesian matriarchal system. Sorabe is an alphabet based on Arabic used to transcribe the Malagasy language and the Antemoro dialect in particular. The Arabs were also the first to correctly identify the origin of most Malagasy by suggesting that the island was colonized by the Indonesians.
