عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ الْغَادِرُ يُرْفَعُ لَهُ لِوَاءٌ يَوْمَ الْقِيَامَةِ يُقَالُ هَذِهِ غَدْرَةُ فُلَانِ بْنِ فُلَانٍ
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: On the Day of Resurrection, a flag will be raised for the deceiver, and it will be announced: This is the deception of so-and-so, son of so-and-so.
