As for the Zirariyya, the name and origin of this sect can be traced to a man called Zirar ibn 'Amr.
According to the teaching of Zirar, the physical bodies or substances [ajsam] are accidents assembled as a conglomerate [a'rad mujtami'a]. He also maintained that it is possible for the accidents to be transformed into physical bodies or substances [an tanqaliba'l-a'radu ajsaman]. He taught that the ability to act [istita'a] is part and parcel of the person who is capable of acting [mustati'], and that it exists prior to the action. He rejected the qira'a [manner of recitation, punctuation and vocalization of the text of the Qur'an] of Ibn Mas'ud and Ubayy ibn Ka'b (may Allah be well pleased with them both).
