"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 conjecture 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. (The Noble Quran, 4:156-159)"
