JACOB BEN NETHANEL BEN FAYYŪMĪ

JACOB BEN NETHANEL BEN (AL-) FAYYŪMĪ (12th century), *nagid of Yemenite Jewry, when ʿAbd al-Nabī ibn al-Mahdī, the ruler of *Yemen, decreed a forced renunciation of Judaism in about 1160. Many Jews converted to Islam and the Messiah's coming was widely awaited. R. Jacob turned for counsel to *Maimonides, who replied in the form of a letter known as Iggeret Teiman ("Epistle to Yemen," c. 1172) in which he sought to strengthen the faith of the Jews of the country.
