1. Jesus, Mary, and the angel Gabriel are all in the Quran (as are Adam, Noah, Abraham, Moses, and a bunch of other Bible characters).
2. Muslims who follow the Quran believe that Jesus (called "Isa" in Arabic) was a prophet of God, was born to a virgin (Mary).
3. Mary (called "Maryam" in Arabic) has an entire chapter in the Quran named for her — the only chapter in the Quran named for a female figure. In fact, Mary is the only woman to be mentioned by name in the entire Quran: As noted in the Study Quran, "other female figures are identified only by their relation to others, such as the wife of Adam and the mother of Moses, or by their title, such as the Queen of Sheba." Mary is mentioned more times in the Quran than in the entire New Testament.
4. Just as with all the other prophets, including Mohammed, Muslims recite, "Peace be upon him" every time they refer to Jesus.
