He hath only forbidden you dead meat, and blood, and the flesh of swine, and that on which any other name hath been invoked besides that of God. - Surat-ul Baqara (2):173
Since the flesh of swine is strongly forbidden in Islam, Muslims regard the eating of pork as an extremely unholy act an abomination before God. For this reason, they consider it an outrageous contradiction for people, who claim to be followers of the holy prophet Jesus, to eat pork.
