Very interesting, N-A-M. Many levels of infighting going on in islam. Thanks ........................ FRegards
After the Profit Mo died, his 3 companions became religious/political leaders (Caliphs) but after the first 4 died, then Mo's son-in-law Ali wanted to be Caliph and he was supported by Mo's 9-yeard old bride Aisha (ok, she was older by this time!) starting the first war and when Mo's grandson Hussein was killed by the Caliphs, that was the start of the Shias
The Ibadis (who dominate Oman) split off at the same time
Among the Sunnis (80% of the worlds Moslems -- but that is because of their domination in Pakistan, Bangladesh and Indonesia and India which together comprise 700 odd million Moslems (70% of all Moslems in the world) there are numerous schools: hanafi etc. -- the Sufis mixed mysticism with Islam and are hated by Wahabbis. Wahabbis and the Deoband school of Islam are detested by other Sunnis.
Among Shias you have twelver (the majority) and 7ers and 5 evers depending on how many Imams they think were "righteous". You have Shias, Ismailis, Bohris, Syedna Bohris etc. -- Ismailis have their own hereditary ruler -- the Aga Khan (who is now a playboy like his dad and has at least 75% European blood as his dad and grandad married various European women (and got divorced and lost a lot of money!)) who gets 10% of the money from Ismailis globally, Syedna Bohris have their own Syedna who is the theocratic ruler. Bohras have a council. Now the Shias believe in interpretation of the Koran, unlike the strict Sunni idea -- no interpretation, take it literally, even the bits about killin'.
And you have others -- Ibadis who are far more peaceful yet have their own Imamate
Then Druze, Allawis, etc. who are really Gnostics or syncretic religions rather than Moslems
And the Ahmadiyyas and Bahai's who have new prophets (after Mo) and are considered the worst kind of heretic by all other Moslems as to say that there was a prophet after Mo is the worst kind of blasphemy!)
