Peace be upon you.
Here is the passages you specified and no where does it mention Judas.
[4:155] (They have incurred divine displeasure): in that they broke their Covenant; that they rejected the Signs of Allah; that they slew the Messengers in defiance of right; that they said, "Our hearts are the wrappings (which preserve Allah's Word; we need no more)"; nay Allah hath set the seal on their hearts for their blasphemy, and little is it they believe.
[4:156] That they rejected Faith; that they uttered against Maryam a grave false charge;
[4:157] That they said (in boast), "We killed Al-Masih 'Isa the son of Maryam, 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.
[4:158] Nay, Allah raised him up unto Himself; and Allah is Exalted in Power, Wise.
[4:159] And there is none of the People of the Book but must believe in him before his death; and on the Day of Judgment he will be a witness against them.
Hope this helps
