@placebo @Tony @freepatriot @d9dba0e072bdb353dfb0020de159126af47e69e133ea91bbd48e8bede37320e2 True but I think it had more to do with jewish influence in the region. Most of Muhammad's debates were with jews, the tenants of the religion more resemble judaism, with bits of Christian lore mixed in from stories he heard on the road and from his first wife. Medina was also a jewish city before Muhammad was forced to drive them out (they wouldn't stop trying to jew him)

There were some Christian heretics in Arabia at the time but they were a minority, whereas diaspora jews were common.
