It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Near the Day of Judgment, the water of the Euphrates River will recede, uncovering a mountain of gold from beneath it. People will begin to fight over it, to the extent that out of every hundred, ninety-nine will be killed. My son, if you reach that time, do not be among those who fight over it.
