What did the Arab Muslim wife say?

1, the founder of Islam is Muhammad. He preaches that the real God in the world is God, and he is a missionary of God. All Muslims call themselves Muslims. The founder of Christianity is Jesus, and the true God he preaches is God. Christianity has many branches. The big branches are Orthodox Church and Catholicism. Both Arabia and Iran are one religion, Islam, but they belong to different sects. Most of Iran is Sunni Muslim, and most of Arab countries are Shia Muslim.

2. Muslims and Islam are the same thing (Arabia and Iran are among them). Catholicism and Christianity were also a family 600 years ago. At the beginning of16th century, a Catholic priest named Martin Luther began the Reformation. So a group of reformers came out of Catholicism, which is now Christianity. They reformed many doctrines in Catholicism, and those reformed doctrines are the differences between Catholicism and Christianity.
