The gharqad (Arabic: غرقد) tree is mentioned in several hadiths that describe Islamic eschatology. It is considered likely that the gharqad tree is genus Nitraria[1] or genus Lycium.[2][3]
An excerpt from a hadith attributed to Abu Huraira (one of Muhammad's companions) is famously quoted in the 1988 founding charter of Hamas, Article 17, stating that every stone and tree—except for the gharqad tree—will speak aloud to reveal if a Jew is taking cover, so that the Muslim army can find and kill the Jew.[4]
Members of the genera Nitraria and Lycium do not have any significance in Judaism.
