As
it happens, according to mainstream Islamic interpretations of Sharia,
proselytizing Muslims is a capital offence. In fact, it is mentioned as
far back as the so-called Pact of Omar, which Muslim doctrinaires still
quote from, and which delineates what non-Muslims (it was first made
with Christians in Syria) must—and must not—do to safeguard their blood.
(meforum.org)(Candid) 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.
