sorry for jumping in but I would like to add a few words
The unique thing in the case of Jesus AS were:
1) His miraculous birth that Jews pointed fingers to
2) The jews wanted to crucify him. Crucifixion was considered to be an accursed death and they believe that if they succeed in their designs, it will be a seal on Jesus being a false prophet (Na auzabillah). A true messenger/prophet of Allah cannot die this way.
That is why Allah assured him that He will not let Jews crucify him or kill him, he will die a natural death. moreover, the charges on Jesus' honour will be washed away.
