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.
[4] The slogan was coined in the late 1980s during the First Intifada by Ahmed Yassin, founder of the militant Palestinian Islamist organization Hamas.
[10][11] It has been chanted at Islamic extremist and pro-Palestinian demonstrations, including in Jerusalem,[12][13] Sweden,[14] England,[15][16][17] Austria,[18] Belgium,[19] the Netherlands,[20][21][22] and Australia.
[23] The chant is employed more frequently during periods of violence between Israel and the Palestinians, like during the 2021 Israel–Palestine crisis and the Gaza war.
