Valke, you must be pulling my leg while saying that Christ’s crucifixion was a kind of deceit!

Deception entails fakery and means making someone to believe in something that’s unreal. The Lord’s passion and death were by no means untrue as well as His resurrection. I am afraid you are interpreting Jesus’ death and resurrection from a Jewish perspective, and your denial of the resurrection makes you assume that the passion was not real either. Nonetheless, the New Testament never claims that Jesus’ death or resurrection was based upon lies or had fake elements.
On the other hand, Allah in the Quran makes a miracle and creates an illusion (a fake Jesus to be crucified) in order to make Jesus’ passion seem real! This aims, of course, to deceive the Jews (make fools of them) through an argument that cannot be debunked easily since it is impossible to prove the opposite.
Be sure that Mohammed’s Allah uses Jesus as a perfect instrument of degrading and mocking the Jews, which is one of the main weapons of the anti-Semitic campaign in the Quran. Jesus in the Gospels is the lamb of God, whose true sacrificial death redeems the humanity whereas Issa son of Meryem in the Quran is a pathetic messenger of Allah, whose fake death enables Mohammed to deride the Jews of his period.
Shalom to you
