Sahih al-Bukhari · Book 58: Jizyah and Mawaada'ah · The sin of a betrayer
Narrated Anas:
حَدَّثَنَا أَبُو الْوَلِيدِ ، حَدَّثَنَا شُعْبَةُ ، عَنْ سُلَيْمَانَ الأَعْمَشِ ، عَنْ أَبِي وَائِلٍ ، عَنْ عَبْدِ اللَّهِ .وَعَنْ ثَابِتٍ ، عَنْ أَنَسٍ ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لِكُلِّ غَادِرٍ لِوَاءٌ يَوْمَ الْقِيَامَةِ ـ قَالَ أَحَدُهُمَا يُنْصَبُ وَقَالَ الآخَرُ ـ يُرَى يَوْمَ الْقِيَامَةِ يُعْرَفُ بِهِ " .
The Prophet (ﷺ) said, ''Every betrayer will have a flag on the Day of Resurrection" One of the two subnarrators said that the flag would be fixed, and the other said that it would be shown on the Day of Resurrection, so that the betrayer might be recognized by it.
