Although the protections afforded Jews and Christians by Islamic law were, in many ways, ahead of their time, this grace, such as it was, had its limits. According to the Pact of Umar, which defined the relationship between the Peoples of the Book,
[Christians, Jews, and Zoroastrians] shall not build, in our cities or in their neighborhood, new monasteries, Churches, convents, or monks’ cells, nor shall we repair, by day or by night, such of them as fall in ruins or are situated in the quarters of the Muslims.
This strict limit was not absolute, in practice. But how interesting that the very groups that oppose Sharia law as a looming threat to the American way of life would now duplicate it, to repress Muslims.
