Ali ibn al-Husayn ibn Ali ibn Muhammad ibn al-Walid (Arabic: علي بن الحسين بن علي بن محمد بن الوليد, romanized: ʿAlī ibn al-Ḥusayn ibn ʿAlī ibn Muḥammad ibn al-Walīd) was the ninth Tayyibi Isma'iliDa'i al-Mutlaq in Yemen, from 1268 to his death in 1284.[1]
Life
He was the son and chief assistant of the eighth Da'i, al-Husayn ibn Ali,[1] and thus a member of the Banu al-Walid al-Anf family that dominated the office of Da'i al-Mutlaq almost continuously in the 13th to early 16th centuries.[1]
Due to intense fighting between the ZaidiImam and the Hamdanids, Ali moved from his original seat at Sanaa to the Hamdanid fortress of Arus. He returned to Sanaa only after it was recaptured by the Hamdanids, and died there.[1] He was succeeded by Ali ibn al-Husayn ibn Ali ibn Hanzala, the grandson of the sixth Da'i, Ali ibn Hanzala, and son of Ali's own ma'dhun (senior deputy).[2]
