Re: Hazrat Isa A.S.
Yes I know … His views give more preference to the idea that Isa (AS) was not killed on the cross, but unfortunately I disagree with him because the Qur’an says he (AS) was not crucified, but Sh. Deedat argues the possibility that he was put on the cross, but not killed on it. For me being put on the cross is being crucified on the cross, despite what definition your prop out from dictionaries - the Arabic is clear. He (AS) was not killed and not crucified.
The idea of substitution is extra scriptural - i.e. from other research outside the Qur’an.
