Upon the death of the twentieth Imam, al-Amir bi-Ahkami'l-Lah (d. AH 526 (1131/1132)), his two-year old child at-Tayyib Abu'l-Qasim (b. AH 524 (1129/1130)) was appointed twenty-first Imam. As he was not in position to run the dawah, Queen Arwa al-Sulayhi, the Da'i al-Mutlaq, acted as his regent. The Da'i had now been given absolute authority and made independent from political activity.
Da'i Zoeb bin Moosa
Da'i Zoeb bin Moosa used to live in and died in Haus, Yemen. His ma'zoon ("associate") was Khattab bin Hasan. After death of Abadullah, Zoeb bin Moosa appointed Yaqub as the wali ("representative" or "caretaker") of the Taiyabi organization ("dawah") in India. Yaqub was the first person of Indian origin to receive this honor. He was son of Bharmal, minister of the Rajput King Jayasimha Siddharaja. Fakhruddin, son of Tarmal, was sent to western Rajasthan. One Da'i after another were continued until the twenty-fourth Da'i, Yusuf Najmuddin ibn Sulaiman, in Yemen. Due to prosecution by a local ruler, the dawah then shifted to India under the twenty-fifth Da'i, Jalal bin Hasan.
In 1592, the Taiyabi broke into two factions in a dispute over who should become the twenty-seventh Da'i: Dawood Bin Qutubshah or Sulayman bin Hassan. The followers of the former, primarily in India, became the Dawoodi Bohra, the latter the Sulaymani of Yemen.
At present, the largest Taiyabi faction is the Dawoodi Bohra, whose current leader is disputed.
