1. Qur'an is very clear that Jesus (Easa) (AS) was never killed nor crucified despite the criminal attempt of his enemies to kill and crucify him, but they killed and crucified a person who looked like him. (Al-Nisaa' 157).
2. Jesus was raised from the earth to the sky (Al-Nisaa' 158).
3. Jesus is still alive in the sky and will come down to the earth and will be a follower and supporter of Imam Al-Mahdi (AS).
