'Abdullah b. Harith b. Naufal reported: 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 Messenger of Allah 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 Abu Ka'b stood under the shade of the battlement of Hassan.

حَدَّثَنَا أَبُو كَامِلٍ، فُضَيْلُ بْنُ حُسَيْنٍ وَأَبُو مَعْنٍ الرَّقَاشِيُّ - وَاللَّفْظُ لأَبِي مَعْنٍ -
قَالاَ حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ، حَدَّثَنَا عَبْدُ الْحَمِيدِ بْنُ جَعْفَرٍ، أَخْبَرَنِي أَبِي، عَنْ سُلَيْمَانَ بْنِ،
يَسَارٍ عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ بْنِ نَوْفَلٍ، قَالَ كُنْتُ وَاقِفًا مَعَ أُبَىِّ بْنِ كَعْبٍ فَقَالَ لاَ يَزَالُ
النَّاسُ مُخْتَلِفَةً أَعْنَاقُهُمْ فِي طَلَبِ الدُّنْيَا . قُلْتُ أَجَلْ . قَالَ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى
الله عليه وسلم يَقُولُ
" 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 " . قَالَ أَبُو كَامِلٍ فِي حَدِيثِهِ قَالَ وَقَفْتُ أَنَا وَأُبَىُّ
بْنُ كَعْبٍ فِي ظِلِّ أُجُمِ حَسَّانَ .
