Ali ibn Hatim
Ali ibn Hatim al-Hamidi was the fourth Tayyibi Isma'ili Dāʿī al-Muṭlaq in Yemen, from 1199 to his death in 1209.
He was chosen by his father, Hatim ibn Ibrahim, as his successor on the recommendation of Hatim's maʾdhūn, Ali ibn Muhammad ibn al-Walid, who had been his tutor. When Hatim died in 1199, Ali succeeded him, still with Ali ibn Muhammad as his maʾdhūn.
During his tenure he was forced to move the headquarters of the Tayyibi daʿwa from the fortress of Hazar to Sanaa, because the Ya'buri family ruling Hazar fell into fratricidal conflict and turned against the Tayyibis. The Hamdanids of Sanaa welcomed him, and their overlords, the Ayyubids, did not oppose his presence in the city.
Ali died on 31 May 1209, and with him ended the Hamidi line. He was succeeded by Ali ibn Muhammad, who founded the Banu al-Walid al-Anf line of Tayyibi Dāʿīs.
