Wael Hallaq states that in theory, Islamic religious tolerance only applied to those religious groups that Islamic jurisprudence considered to be monotheistic "People of the Book", i.e. Christians, Jews, and Zoroastrians if they paid the "jizya" tax, while to those excluded from the "People of the Book" were only offered two choices: convert to Islam or fight to the death. In practice, the "People of the Book" designation and "dhimmi" status were even extended to the non-monotheistic religions of the conquered peoples, such as Hindus, Jains, Buddhists, and other non-monotheists.
