Hadith 1820

Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah(PBUH) said, "The Last Hour will not come until the Muslims fight against the Jews, until a Jew will hide himself behind a stone or a tree, and the stone or the tree will say: 'O Muslim, there is a Jew behind me. Come and kill him,' but Al-Gharqad tree will not say so, for it is the tree of the Jews."
