Messenger of Allah ﷺ said, "The Hour will not be established till a fire will come out of the land of Hijaz, and it will throw light on the necks of the camels at Busra."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ تَقُومُ السَّاعَةُ حَتَّى تَخْرُجَ نَارٌ مِنْ أَرْضِ الْحِجَازِ تُضِيءُ أَعْنَاقَ الإِبِلِ بِبُصْرَى  

Messenger of Allah ﷺ said, "Soon the river "Euphrates" will disclose the treasure (the mountain) of gold, so whoever will be present at that time should not take anything of it." Al-A'raj narrated from Abii Huraira that the Prophet ﷺ said the same but he said, "It (Euphrates) will uncover a mountain of gold (under it).  

رَسُولُ اللَّهِ ﷺ يُوشِكُ الْفُرَاتُ أَنْ يَحْسِرَ عَنْ كَنْزٍ مِنْ ذَهَبٍ فَمَنْ حَضَرَهُ فَلاَ يَأْخُذْ مِنْهُ شَيْئًا قَالَ عُقْبَةُ وَحَدَّثَنَا عُبَيْدُ اللَّهِ حَدَّثَنَا أَبُو الزِّنَادِ عَنِ الأَعْرَجِ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ مِثْلَهُ إِلاَّ أَنَّهُ قَالَ يَحْسِرُ عَنْ جَبَلٍ مِنْ ذَهَبٍ
