حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ حَدَّثَنَا عُبَيْدُ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا جَمَعَ اللَّهُ الْأَوَّلِينَ وَالْآخِرِينَ يَوْمَ الْقِيَامَةِ رُفِعَ لِكُلِّ غَادِرٍ لِوَاءٌ فَقِيلَ هَذِهِ غَدْرَةُ فُلَانِ بْنِ فُلَانٍ
مسند امام احمد بن حنبل · Hadith 4839
It was narrated that lbn 'Umar said: The Messenger of Allah (PBUH) said: "When Allah gathers together the first and the last on the Day of Resurrection, a banner will be raised for every betrayer and it will be said: This is the betrayal of So and so the son of So and so."
