It's in the Qur'an: Suras 2:62-65, 5:59-60, and 7:166. Why then should we be surprised when Muslim spokesmen call Jews apes and pigs? From IMRA, with thanks to Alyssa Lappen:
Gaza Palestine Satellite TV Channel in Arabic, official television station of the Palestinian Authority, carries on 13 March 2004 at 0958 GMT a live sermon from Zayid Bin-Sultan Mosque in Gaza.
Shaykh Ibrahim Mudayris delivers the sermon, which he begins by saying that life is a continuous struggle between right and falsehood and that such a struggle exists in the territories between Palestinians and Jews. The Palestinians, he says, are defending a just cause and will triumph in the end.
The imam recalls how the prophet dealt with the problem of Jewish existence before establishing the State of Islam in Medina. He says that the prophet first fraternized the warring Arab tribes of Al-Aws and Al-Khazraj. Then victory in the Battle of Badr gave him the military strength to deal with Jewish existence in Medina, he adds.
The imam says: "Here are the Jews today taking revenge for their grandfathers and ancestors, the sons of apes and pigs. Here are the extremist Jews demanding their rights. Some extremists even demand their rights in Medina."
He adds: "This is the extremist tendency of Jews. They are extremists and terrorists who deserve death, while we deserve life, since we have a just cause. Here they are avenging for their grandfathers, taking revenge on us, Muslims, by seizing our holy places and lands forcefully. Last week was a bloody week in which they killed 40 youths, children, and women within the sight of the whole world. No one made a move against these massacres."
