Arabic hadith text
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَحْيَى بْنُ آدَمَ، عَنْ يَزِيدَ بْنِ عَبْدِ الْعَزِيزِ، عَنِ الأَعْمَشِ، عَنْ شَقِيقٍ، عَنْ عَبْدِ اللَّهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم "لِكُلِّ غَادِرٍ لِوَاءٌ يَوْمَ الْقِيَامَةِ يُعْرَفُ بِهِ يُقَالُ هَذِهِ غَدْرَةُ فُلاَنٍ "
Translation
It has been narrated on the authority of Abdullah that the Messenger of Allah (ﷺ) said
There will be for every perfidious person on the Day of Judgment a flag by which he will be recognised. It will be announced: Here is the breach of faith of so and so.
