Narrated Jabir bin Samura:

The Prophet ﷺ said, "If Caesar is ruined, there will be no Caesar after him;
and if Khosrau is ruined, there will be no Khosrau, after him;
and, by Him in Whose Hand my soul is, surely you will spend their treasures in Allah's Cause."

حَدَّثَنَا مُوسَى، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ عَبْدِ الْمَلِكِ، عَنْ جَابِرِ بْنِ سَمُرَةَ، عَنِ النَّبِيِّ ﷺ قَالَ " إِذَا هَلَكَ قَيْصَرُ فَلاَ قَيْصَرَ بَعْدَهُ، وَإِذَا هَلَكَ كِسْرَى فَلاَ كِسْرَى بَعْدَهُ، وَالَّذِي نَفْسِي بِيَدِهِ لَتُنْفَقَنَّ كُنُوزُهُمَا فِي سَبِيلِ اللَّهِ ".
