How did the oaths of the Prophet (saws) use to be? Sahih al-Bukhari 6629
Arabic hadith text
حَدَّثَنَا مُوسَى، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ عَبْدِ الْمَلِكِ، عَنْ جَابِرِ بْنِ سَمُرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ "إِذَا هَلَكَ قَيْصَرُ فَلاَ قَيْصَرَ بَعْدَهُ، وَإِذَا هَلَكَ كِسْرَى فَلاَ كِسْرَى بَعْدَهُ، وَالَّذِي نَفْسِي بِيَدِهِ لَتُنْفَقَنَّ كُنُوزُهُمَا فِي سَبِيلِ اللَّهِ "
Translation
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."
