" know, that the mutazilah parted into 17 factions. 1. ghaylaniyyah: followers of ghaylan al-dimashqi  this faction gathers [heresies] of iytizal and irjaa . it is this ghaylan who was executed by hisham ibn abd al-malik, the seventh khalifah of banu marwan. 2. waSiliyyah: followers of waSil ibn `aTa al-ghazzal  he was the first to say that the sinner [fasiq] is neither a kafir, nor a believer, nor a hypocrite, nor a polytheist. according to this faction, [the Companions] `ali and TalHah raDiyallahu anhuma, if they both bore witness in the same matter, their [combined] witness is invalid. however if each of the two bore witness, such that each of the two had another person with them, then their witness can be accepted. 3. `amariyyah: the followers of `amr ibn `ubayd. according to them the witness of TalHah and zubayr is absolutely invalid, regardless of the combination. 4. huzayliyyah  followers of abu huzayl .according to this faction the Power of Creation of Allah ta'ala has ended and reached such a stage that He cannot create anything new. 5. naZZamiyyah: followers of ibrahim ibn sayyar al-naZZam. according to this faction, a slave [creation] has power to do things which Allah ta'ala does not have upon His creation. according to them, ijma', lone-narrator reports and analogical reasoning have no legal standing in shar'iah. [laysa bi Hujjah]. however, they do not criticise or speak ill of the Companions nor ali raDiyallahu anhu. 6. thumamiyyah: the followers of thumamah ibn ashras.[d. 213 AH] he lived in the time of ma'mun. according to them an action can occur even if there is no actor (by whose act the action materialises). 7. bishriyyah: the followers of bishr ibn mu'ammar ibn `ubbad al-sullami [d. 226 AH]; this faction affirms on the rational soul [nafs al-naTiqah] similar to the belief of philosophers [see plato's tri-partite soul: rational soul, spirited soul and appetitive soul]. and they also attest that bodies can have attributes of being infinite. [in two different editions: both my hard copy and a PDF the eighth faction is missing; i suppose this is because of a mixup of bishr ibn mu'tamar and mu'ammar ibn ubbad thus omitting the eighth faction. actually, in milal wa'n niHal of shahrastani, they are two people: bishr ibn mu'tamar with taa, the leader of bishriyyah; and mu'ammar ibn ubbad al-sullami, the leader of mu'ammariyyah; this i believe is the eighth missing in our copies.] 9. muzdariyyah:  followers of abu musa ibn yisa ibn masih al-muzdar . he was the disciple of bishr and the teacher of ja'afar ibn al-Harith  and ja'afar ibn al-mubash'shir. 10. hishamiyyah: the followers of hisham ibn `umar al-quti. he would prohibit from saying: "Allah ta'ala is sufficient for us, and He is the Best Dispenser of Affairs" [Hasbuna Allah wa niymal wakil] because according to him, it is not permissible to use the word 'wakil' for Allah ta'ala. 11. jaHiziyyah: followers of `amr ibn baHr al-jaHiZ. according to this faction, knowledge is essential by nature and it is not gained by action of [one who acquires knowledge]. 12. jubba'yiyyah: followers of muHammad ibn abd al-Wahhab al-jubbayi. according to this faction that the same accident [`araD in something] can be existent and non-existent at the same time. and thus they described the Divine Speech of ALlah ta'ala. 13. [not mentioned in either copies] 14. bahshamiyyah: followers of abu hashim or abu bahsham. abd al-Salam ibn abi ali al-jubbayi.[d. 321 AH] this faction believed in the State of Being [Haal; that is Divine Attributes are states; for example, Samiy is a state; BaSir is a state..] they also consider it possible that Allah ta'ala may punish a slave without his committing a sin. 15. aHshadiyyah: followers of aHshad ibn abi bakr, the student of muHammad ibn umar al-Saymari. they do takfir of abu hashim [above] and his followers. 16. khayyaTiyyah: followers of abu'l Hasan abd al-Rahim al-khayyaT [d. 300AH] and he is the teacher of abu'l qasim al-ka'abi . this faction says, that a body which was non-existent [`adam] is a body; so much that they say "a rider on a horse [both] non-existent." is a thing . 17. Husayniyyah: followers of abu'l Husayn ali ibn Muhammad al-baSri. he is the disciple of qaDi abd al-Jabbar ibn aHmad. thereafter, he opposed him and rejected the doctrine of "states" and "non-existent" and "meaning" and accepted that miracles of the friends of Allah [karamat al-awliya] and refuted the muridiyyah; though he was non-commital about the Divine Attributes of 'Hearing' and 'Seeing'. most of these factions of the mutazilah [died away and] didn't remain until our time except these two factions of abu hashim [see #14 above] and abu'l Husayn al-baSri [#17 above]. end of razi's text."
