Sunan Abi Dawud, Hadith 2750 ⓘ
Ibn ‘Umar reported the Apostle of Allaah as saying “A banner will be hoisted for a treacherous man on the Day of Judgment, it will then be announced. This is a treachery of so and so, son of so and so.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِنَّ الْغَادِرَ يُنْصَبُ لَهُ لِوَاءٌ يَوْمَ الْقِيَامَةِ فَيُقَالُ هَذِهِ غَدْرَةُ فُلاَنِ بْنِ فُلاَنٍ " .
