States People Centers Other Abūʾl-Qāsim al-Ṭayyib ibn al-Āmir (أبو القاسم الطيب بن الآمر) was, according to the Tayyibi sect of Isma'ilism, the twenty-first imam.
Amidst the ensuing power struggle, al-Tayyib disappeared; modern historians suggest that he died or was secretly killed by one of the rival strongmen.
[4][5] What happened next appears to have effectively been a coup: two of al-Amir's favourites, Hizar al-Mulk Hazarmard (or Jawarmard) and Barghash, who had influence over the army, allied themselves with Abd al-Majid, to control the government.
Modern scholars speculate that al-Tayyib may have died in infancy, possibly even before his father; but at least one contemporary anonymous Syrian source maintains that he was murdered on Abd al-Majid's orders.
[17] The only dissenting account is that of the 15th-century Tayyibi leader and historian Idris Imad al-Din, who explicitly claims that Abd al-Majid took office as regent for al-Tayyib.
[25][24][26] Al-Hafiz's highly irregular accession and claims to the imamate were largely accepted by the Isma'ili faithful in the Fatimid domains in Egypt, Nubia, and the Levant, but rebuffed by some communities.
Most notably, this was the case in the only other major Isma'ili realm, Yemen, where Queen Arwa upheld the rights of al-Tayyib, while the subordinate regional dynasties of the Hamdanids and the Zurayids recognized al-Hafiz's claims.
