The article presents the doctrine of muhammisa according to Muslim heresiography. 
The muẖammisa is one of  ḡulāt  groups. This term is applied to groups accused of 
exaggeration (ḡuluww) in religion and has covered a lot of groups from the early Šī‘ī 
circle. Muhammisa is a current without a specific leader, it seems to have been a group 
of partisans having propagated a very particular idea: the divinity of five persons from 
ahl al-kisā’: Muhammad, ‘Alī, Al-Hasan, Al-Husayn and Fātima. The article focuses on 
their doctrines as presented by the heresiographers and their relation to another group, 
‘alyā’iyya, who recognised ‘Alī as God and Muhammad as his servant.
