The Jews of Islam (1984) is a book written by Middle-East historian and scholar Bernard Lewis.
Regarding Jews in Islamic lands, he states: Generally, the Jewish people were allowed to practice their religion and live according to the laws and scriptures of their community.
That is to say, these regulations served to define the relationship between the two communities, and not to oppress the Jewish population.
[1]The author also claims: "For Christians and Muslims alike, tolerance is a new virtue, intolerance a new crime.
Until comparatively modern times, Christian Europe neither prized nor practiced tolerance itself, and was not greatly offended by its absence in others.
