the Quran doesn't say that. in chapter 4 verse 156-159 the Quran
says
4:156-159 "That they rejected Faith; That they uttered against Mary
A grave false charge; That they said (in boast): 'We killed
Christ Jesus The son of Mary, The Messenger of Allah.' But they
killed him not, Nor crucified him, but so it was made to
appear to them, and those who differ therein are full of doubts,
with no (certain) knowledge, but only conjunction to follow, for of
a surety they killed him not. Nay, Allah raised him up Unto
Himself; and Allah Is Exalted in Power, Wise. And there is
none of the people of the book (Jews and Christians) But
must believe in him (Jesus) Before his death; And on the
Day of Judgment He (Jesus) will be a witness Against
them."
