Salaam.
In the Qur'an prior to 4:157 it states "Don’t say that those killed in Allah’s* path are dead, but alive, though you don’t realize it." (QS 2:154). The question is, does 2:154 apply to Jesus, or didn't he qualify?
It does not ask us not to say that they were killed. They were killed, for all practical purposes. But, as in the temporal realm, doctors - purportedly the really knowledgeable - sometimes declare those who are seemingly killed by disease, or any other cause, alive, even so in the spiritual realm, about those considered dead by ordinary folk because they are witness to them having been killed, the Creator Himself declares the truth that those killed in the path of God as alive.
That Jesus was neither killed nor crucified, is the truth.
