A Palestinian preacher recently issued a threat to Jews in an impromptu sermon at the al-Aksa Mosque: "We shall slaughter you without mercy."The video translated by MEMRI on Sunday, shows a sermon by Sheik Omar Abu Sara which was posted to the internet on November 28.Abu Sara is seen in the video surrounded by dozens of worshipers, telling them that all of the "vile traits" attributed to the Jews in the Koran remain the same today, and in fact, the Jews "have become even more vile and evil.""By Allah, the Jews are the most evil of Allah's creations," Abu Sara said. "They are the most evil creatures to have walked this Earth."He referred to Jews as "the slayers of prophets," adding that "it was the Jews that Allah had turned into apes and pigs."He said that the battle with the Jews had drawn near in current times. He quoted the Prophet Muhammad as saying, "You will fight the Jews until the trees and the stones will say: 'Oh servant of Allah, oh Muslim, there is a Jew behind me. Come and kill him."Abu Sara appeared to ally himself with the goals of terror group, Islamic State, saying that he hoped Allah would hasten the coming of the Islamic Caliphate."I say to the Jews loud and clear: The time for your slaughter has come. The time to fight you has come. The time to kill you has come Allah willing, we are ready for the task, we and the loyal and faithful Muslims, along with the armies of the state of the Islamic Caliphate, which will come to liberate this land from your filth.""Oh Allah, hasten the establishment of the state of the Islamic Caliphate."
