Jesus, Mary, and the angel Gabriel are all in the Quran (as are Adam, Noah, Abraham, Moses, and more!
Muslims believe that Jesus (called "Isa" in Arabic) was a prophet of God, was born to virgin Mary, and will return to Earth before the Day of Judgment to restore justice and to defeat the Antichrist. All of which may sound pretty familiar to many Christians.
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: Mary is mentioned more times in the Quran than in the entire New Testament.
Just as with all the other prophets, including Mohammed, Muslims recite, "Peace be upon him" every time we refer to Jesus.
Muslims believe that Jesus performed miracles: The Quran discusses several of Jesus's miracles, including giving sight to the blind, healing lepers, raising the dead, and breathing life into clay birds.
