Mishkat al-Masabih 27 Fitan كتاب الفتن 64

وَعَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: ” لَا تَقُومُ السَّاعَةُ حَتَّى يَحْسِرَ الْفُرَاتُ عَنْ جَبَلٍ مِنْ ذَهَبٍ يَقْتَتِلُ النَّاسُ عَلَيْهِ فَيُقْتَلُ مَنْ كُلِّ مِائَةٍ تِسْعَةٌ وَتِسْعُونَ وَيَقُولُ كُلُّ رَجُلٍ مِنْهُمْ: لَعَلِّي أَكُونُ أَنَا الَّذِي أنجُو ” . رَوَاهُ مُسلم

He reported God’s messenger as saying, “The last hour will not come before the Euphrates uncovers a mountain of gold for which people will fight, ninety-nine out of each hundred of whom will be killed; but every man among them will say that perhaps he will be the one who will escape.” Muslim transmitted it.
