Can you tell us about the claim that `Isa (Jesus, peace be upon him) was crucified but did not die on the Cross.
Allah (Exalted be He) spoke about the claim of
the Jews that they killed `Isa (peace be upon him), the son of Maryam (Mary, peace be upon her). Allah (Exalted be He) refuted this alleged claim stating explicitly that `Isa was neither killed nor crucified. Allah (Exalted be He) says:
And because of their saying (in boast), "We killed Messiah ‘Isâ (Jesus), son of Maryam (Mary), the Messenger of Allâh," - but they killed him not, nor crucified him, but it appeared so to them [the resemblance of ‘Isâ (Jesus) was put over another man (and they killed that man)], and those who differ therein are full of doubts. They have no (certain) knowledge, they follow nothing but conjecture. For surely; they killed him not [i.e. ‘Isâ (Jesus), son of Maryam (Mary) عليهما السلام]:
But Allâh raised him [‘Isâ (Jesus)] up (with his body and soul) unto Himself (and he عليه السلام is in the heavens). And Allâh is Ever All-Powerful, All-Wise.
Whoever claims that `Isa (peace be upon him) was crucified or killed is a Kafir as he will be opposing the explicit texts of the Qur'an.
