On July 21, the Egyptian-born American preacher Ammar Shahin delivered a Friday sermon at the Islamic Center of Davis, northern California, where he serves as Imam. In it he cited an antisemitic hadith, according to which the Muslims would fight the Jews on Judgment Day, and prayed to Allah to “liberate the Al-Aqsa Mosque from the filth of the Jews” and to “annihilate them down to the very last one,” not sparing any of them. “Oh Allah, make this happen by our hands. Let us play a part in this,” he prayed in the sermon, which was posted on the Davis Masjid YouTube channel. Imam Shahin, who had earned a B.A. in Islamic studies in Egypt, traveled in 1999 to the U.S., where he obtained a degree in computer engineering. He is listed as an instructor of the Zidni Islamic Institute, a California-based organization that teaches Sunni Islam in the West.
