“They did not kill him”
One of the major points of divergence between Islam and Christianity is that, in addition to denying Jesus’ divinity, Islam asserts that Jesus did not die on the cross. We find this assertion in Surah 4 of the Qur’an:
Just in case you don’t read Arabic(!), here is the English translation:
[They said] “Indeed, we have killed the Messiah, Jesus, the son of Mary, the messenger of Allah”… [But] they did not kill him, nor did they crucify him; but [another] was made to resemble him to them… Rather, Allah raised him to Himself… – Surah 4:157-158, Sahih International
