.. 278 – Abu al Qāsim Hafs bin ‘Umar narrated to us, he said: Abū Hātim al Rāzī narrated to us, he said: Yahyā bin Zakariyyā bin ‘Īsā narrated to us, he said: Hafs bin Humayd said: I said to ‘Abdullah bin Mubārak:
How many sects did this Ummah split into?
So he (‘Abdullah bin Mubārak) said,
“The foundations are four sects: they are the Shī’ah, the Harūriyyah (i.e. Khawārij), the Qadariyyah and the Murji’ah –
Then the Shī’ah split into 22 sects
the Harūriyyah split into 21 sects
the Qadariyyah split into 16 sects
and the Murji’ah split into 13 sects.”
He said: I said: O Abā ‘Abdirrahmān, I didn’t hear you mention the Jahmiyyah.
He (‘Abdullah bin Mubārak) responded, «You only asked me about the sects of the Muslims».
