فَٱخۡتَلَفَ ٱلۡأَحۡزَابُ مِنۢ بَيۡنِهِمۡۖ فَوَيۡلٞ لِّلَّذِينَ ظَلَمُواْ مِنۡ عَذَابِ يَوۡمٍ أَلِيمٍ

Fakhtalafal ahzaabu min bainihim fa wailun lil lazeena zalamoo min 'azaabi Yawmin aleem

But sects from among themselves fell into disagreement: then woe to the wrong-doers, from the Penalty of a Grievous Day!

— Az-Zukhruf (ٱلزُّخْرُف), 43:65
