The hour of judgment shall not come until the Muslims fight the Jews and kill them, so that the Jews hide behind trees and stones, and each tree and stone will say: 'Oh Muslim, oh servant of Allah, there is a Jew behind me, come and kill him,' except for the Gharqad tree, for it is the tree of the Jews."
From Hamas Charter, as recorded in the Hadith collections of Bukhari and Muslim
It is no secret that there are Palestinian Arab imams preaching hate against Israel and against Jews.
It is not even surprising that this preaching of hatred has expanded to outside the Middle East, and has found a home in Europe, where the favorite Hadith of Hamas can be heard, promising the death of Jews.
What is surprising is that last year Muslim Antisemitism, with all its vitriolic hatred, has found its way into the US. It is not as if Antisemitism did not already exist. It's just that generally it has not been as out in the open nor expressed as violently as we have seen it elsewhere.
