Zaydiyya聽is a branch of the聽Shi鈥榓聽arising out of the abortive revolt of Zayd b. 鈥楢li b. al-Husayn in Kufa in 122 AH / 740 CE. During the preparations for the revolt, a part of the Kufan聽Shi鈥榓聽withdrew their support from Zayd in protest against his refusal to condemn unconditionally the early caliphs preceding 鈥楢li and backed Zayd鈥檚 nephew Ja鈥榝ar al-Sadiq as their聽imamIn general usage, a leader of prayers or religious leader. The Shi’i restrict the term to their spiritual leaders descended from 士Al墨 b. Ab墨 峁乴ib and the Prophet’s daughter, Fatima.. This schism led to a lasting division of the聽Shi鈥榓聽into a radical and a moderate wing in terms of their religious break with the Sunni Muslim community. The聽Zaydiyya, as the moderates, did not classify the Sunni Muslims generally as infidels. In political terms, however, they were, in contrast to the radical but quietist聽Imamiyya, militant, espousing revolt against the illegitimate Sunni rule as a religious duty.
