Second Coming
The Second Coming (sometimes called the Second Advent or the Parousia) is a Christian and Islamic belief regarding the future (or past) return of Jesus Christ after his ascension to heaven about two thousand years ago. The idea is based on messianic prophecies and is part of most Christian eschatologies.
Messiah
The Quran identifies Jesus (Isa) as the messiah ("Masih"), who will one day return to earth. At the time of the second coming, "according to Islamic tradition, Jesus will come again and exercise his power of healing. He will forever destroy falsehood, as embodied in the Daj-jal, the great falsifier, the anti-Christ. Then God will reign forever."
