Calling the people by their father's name
Sahih Bukhari
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " الْغَادِرُ يُرْفَعُ لَهُ لِوَاءٌ يَوْمَ الْقِيَامَةِ، يُقَالُ هَذِهِ غَدْرَةُ فُلاَنِ بْنِ فُلاَنٍ ".
Narrated Ibn `Umar: The Prophet (ﷺ) said, "For every betrayer (perfidious person), a flag will be raised on the Day of Resurrection, and it will be announced (publicly) 'This is the betrayal (perfidy) of so-and-so, the son of so-and-so.' "
