Sahih International: And [for] their saying, "Indeed, we have killed the Messiah, Jesus, the son of Mary, the messenger of Allah." And they did not kill him, nor did they crucify him;
but [another] was made to resemble him to them. And indeed, those who differ over it are in doubt about it. They have no knowledge of it except the following of assumption. And they did not kill him, for certain.
Pickthall: And because of their saying: We slew the Messiah, Jesus son of Mary, Allah's messenger -
they slew him not nor crucified him, but it appeared so unto them; and lo! those who disagree concerning it are in doubt thereof; they have no knowledge thereof save pursuit of a conjecture; they slew him not for certain.

(in boast), "We killed Messiah 'Iesa (Jesus), son of Maryam (Mary), the Messenger of Allah," -
but they killed him not, nor crucified him, but the resemblance of 'Iesa (Jesus) was put over another man (and they killed that man), and those who differ therein are full of doubts.

Arberry: and for their saying, 'We slew the Messiah, Jesus son of Mary, the Messenger of God' --
yet they did not slay him, neither crucified him, only a likeness of that was shown to them. Those who are at variance concerning him surely are in doubt regarding him; they have no knowledge of him, except the following of surmise; and they slew him not of a certainty -- no indeed;
