Tāyyib’īyyah/Tāyyibī fiqh or Mustā‘līyyah/Mustā‘lī fiqh is a fiqh system associted with the Mustā‘lī branch of Ismailism that split with the Fatimid supporting Hafizi branch by believing Taiyab abi al-Qasim was the rightful Imam. They are the surviving branch of the Mustaali and have split into Dawoodi Bohra, Sulaimani Bohra, Alavi Bohra and Qutbi Bohra. Dawoodi Bohra is shown to have a succession issue.
Upon the death of the 20th Imam Al-Amir(d.526AH), his Two year old Child Tayyib (b.524 AH) was appointed 21st Imam, as he was not in position to run the Dawa, Queen Arwa al-Sulayhi was authorized by Imām Al-Amir to run the matter considering the situation that prevailed at the time. The Dai had now been given absolute authority and called Dai-ul-Mutlaq and made independent from political activity. Because of the Fatimid Dawat was able to survive even after the fall of Sulehid Dynasty.
Dā'ī Zoeb used to live in and died in Haus, Yemen. His mazoon was Syedna Khattab bin Hasan. Dā'ī Zoeb appointed Maulai Yaqoob (after death of Maulai Abadullah) who was wali ("representative" or "caretaker") in India of the Taiyabi dawat. Moulai Yaqoob was the first person of Indian origin to receive this honour. He was son of Moulai Bharmal, minister of Rajput King Siddhraja Jaya Singha. They all along with minister Moulai Tarmal had honoured Fatimid Dawat along with their fellow citizens on the call of Moulai Abdullah. Moulai Fakhruddin son of Moulai Tarmal was sent to western Rajasthan, India. One Dai after another were continued till 24th Dai Yusuf Najmuddin ibn Sulaiman in Yemen. Due to prosecution by local ruler the Dawat then shifted to India under 25th Dai Jalal bin Hasan.
In 1592, the Taiyabi broke into two factions in a dispute over who should become the 27th Dai: Dawūd Burhanu d-Dīn Qutb Shāh or Sulayman bin Hassan. The followers of the former, primarily in India, became the Dawoodi, the latter the Sulaymani of Yemen.
At present the largest Taiyabi-descended faction, the Dawoodi Bohra Dawa is headed by 53rd dai Syedna Mufaddal Saifuddin who has been appointed after the sudden death of 52nd Dai Syedna Mohammed Burhanuddin. The Sulaimani Bohra are headed by their 52nd Dai, al-Fakhrī ‘Abdullāh ibn Muhammad al-Makrami. The Qutbi Bohra are headed Khuzaima Qutbuddin.
