In Is Islam Luring the Christian Church Into Denying Jesus? Converted Imam Answers, Samuel Smith, we have the following:
Dr. Mark Christian, a former prominent Muslim from Egypt whose great uncle was a co-founder of Muslim brotherhood and is now a Christian lecturer with the goal of warning people about the impact of Islam on the world today, conducted a webinar on March 21 titled "Is Islam Luring the American Church Into Denying Jesus?"
...
Christian asserted that Muhammad died before he could formally end the war against Christians and Jews, meaning that, according to Islam, Muslims have a standing war against Christians and Jews.
It sounds like Islamophobic nonsense to me, but there might some treaty or something that he's referring to that I'm unaware of. Also, it looks like Dr. Christian has some knowledge (maybe a little knowledge) of Islam.
If so, it must be a technicality, as Muslims, Jews, and Christians coexist peacefully in most places throughout the world. And the places where there's not peace, virtually everyone seems to want peace.
Question: Are Muslims technically at war with Christians and Jews?
