"‏ يُوشِكُ الْفُرَاتُ أَنْ يَحْسِرَ عَنْ جَبَلٍ مِنْ ذَهَبٍ فَإِذَا سَمِعَ بِهِ النَّاسُ سَارُوا إِلَيْهِ فَيَقُولُ مَنْ عِنْدَهُ لَئِنْ تَرَكْنَا النَّاسَ يَأْخُذُونَ مِنْهُ لَيُذْهَبَنَّ بِهِ كُلِّهِ قَالَ فَيَقْتَتِلُونَ عَلَيْهِ فَيُقْتَلُ مِنْ كُلِّ مِائَةٍ تِسْعَةٌ وَتِسْعُونَ ‏"

I was standing along with Ubayy b. Ka`b and he said: The opinions of the people differ in regard to the achievement of worldly ends. I said: Yes, of course. Thereupon he said: I heard Allah's Messenger (ﷺ) as saying: The Euphrates would soon uncover a mountain of gold and when the people would bear of it they would flock towards it but the people who would possess that (treasure) (would say): If we allow these persons to take out of it they would take away the whole of it. So they would fight and ninety-nine out of one hundred would be killed. Abu Kamil in his narration said: I and Ubayy b. Ka`b stood under the shade of the battlement of Hassan.
