Muslims deny the crucifixion.
Quran 4:157 (Y. Ali) 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:-
Muslims deny that Christ is God.
Quran 5:17 (Y. Ali) In blasphemy indeed are those that say that Allah is Christ the son of Mary. Say: "Who then hath the least power against Allah, if His will were to destroy Christ the son of Mary, his mother, and all every - one that is on the earth? For to Allah belongeth the dominion of the heavens and the earth, and all that is between. He createth what He pleaseth. For Allah hath power over all things."
If we are to say that Muslims worship the same God as we do then Christianity is a big joke. The crucifixion never happened and we are the biggest fools who ever inhabited this planet.
Muhammed said he got these revelations directly from an Angel. Who is the Angel that would say these things? Who is the Angel that would stand to gain from teaching these things?
