وَلَقَدْ أَرْسَلْنَا مِن قَبْلِكَ رُسُلًا إِلَىٰ قَوْمِهِمْ فَجَآءُوهُم بِٱلْبَيِّنَٰتِ فَٱنتَقَمْنَا مِنَ ٱلَّذِينَ أَجْرَمُوا۟ ۖ وَكَانَ حَقًّا عَلَيْنَا نَصْرُ ٱلْمُؤْمِنِينَ
Verily We sent before thee (Muhammad) messengers to their own folk. Then we took vengeance upon those who were guilty (in regard to them). To help believers is ever incumbent upon Us.
