Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "The Hour will not occur until the Euphrates recedes, uncovering a mountain of gold over which people will fight. Ninety-nine out of every hundred will be killed. Every man among them will say: 'I might be the one who survives.'" Another narration states: “Soon the Euphrates will recede uncovering a treasure of gold. Whoever is present at this event should not take anything from it.”
عن أبي هريرة -رضي الله عنه- مرفوعاً: «لا تقوم الساعة حتى يحسر الفرات عن جبل من ذهب يُقْتَتَلُ عليه، فَيُقْتَلُ من كل مائة تسعة وتسعون، فيقول كل رجل منهم: لعلي أن أكون أنا أنجو». وفي رواية: «يوشك أن يحسر الفرات عن كنز من ذهب، فمن حضره فلا يأخذ منه شيئا».
شرح الحديث :
Our noble Prophet (may Allah’s peace and blessings be upon him) informs us that close to the establishment of the Hour, the River Euphrates will uncover a treasure of gold or a mountain of gold, meaning the gold will come out as a mountain; and people will fight over it because it is one of the trials. Then he forbids those who witness that incident from taking out of it, because no one will be saved from it. Perhaps some of those who witness that event interpret this Hadīth in a way that alters its true meaning, in order to justify for himself taking from it, we seek refuge with Allah from trials.
