Khaybar Khaybar ya yahud

"Khaybar, Khaybar, ya yahud! Jaish Muhammad soufa yaʿoud!" (Arabic: خيبر خيبر يا يهود جيش محمد سوف يعود; lit. 'Khaybar, Khaybar, oh Jews! The army of Muhammad will return!') is an Arabic-language rallying slogan referencing the Battle of Khaybar of 628 CE, which began after Muhammad marched with a large Muslim army and besieged Khaybar, an oasis in present-day Saudi Arabia that was home to a notable Jewish community.

The slogan is chanted primarily at public anti-Israel demonstrations, though it has been invoked during Islamist terrorist attacks as well.

The chant has been categorized as antisemitic by the American news broadcaster PBS and the Israeli newspaper The Times of Israel, and by the British advocacy group Muslims Against Antisemitism and the American advocacy group Anti-Defamation League.
