عَنْ أَبِي هُرَيْرَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ ”إِذَا هَلَكَ كِسْرَى فَلَا كِسْرَى بَعْدَهُ وَإِذَا هَلَكَ قَيْصَرُ فَلَا قَيْصَرَ بَعْدَهُ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَتُنْفِقُنَّ كُنُوزَهُمَا فِي سَبِيلِ اللَّهِ“
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: When Kisra (the Persian emperor) is destroyed, there will be no Kisra to succeed him, and when Caesar (the Roman emperor) is destroyed, there will be no Caesar after him, meaning their kingdoms will come to an end. By Allah! You will certainly, certainly spend their treasures in the way of Allah.
