Fayruz al-Daylami, also spelt
Firuz al-Daylami, belonged to the descendants (''
abna''') of the Persians who had been sent by
Khosrow I to
Yemen, conquered it, and drove out the
Abyssinians. He had two wives who were sisters. As a result of his conversion to Islam, he divorced one wife on the order of the Islamic prophet
Muhammad, since a Muslim cannot simultaneously have as wives two women who are biological sisters. Later, in 632, after
Aswad Ansi claimed prophethood in Yemen and proceeded to invade
Najran and much of Yemen—attacking
Sanaa and killing the ruler of Yemen, Shahr, son of Badhan—Fayruz was sent by Muhammad to kill Aswad. In
al-Tabari's History, Muhammad is reported as saying, "He was killed by the virtuous man Fayruz al-Daylami." However, some sources mention that he governed the region of Sanaa and died later, in 673, during the reign of
Mu'awiya I. ==See also==
