وَمَا ظَلَمْنَٰهُمْ وَلَٰكِن ظَلَمُوٓا۟ أَنفُسَهُمْ ۖ فَمَآ أَغْنَتْ عَنْهُمْ ءَالِهَتُهُمُ ٱلَّتِى يَدْعُونَ مِن دُونِ ٱللَّهِ مِن شَىْءٍۢ لَّمَّا جَآءَ أَمْرُ رَبِّكَ ۖ وَمَا زَادُوهُمْ غَيْرَ تَتْبِيبٍۢ
We wronged them not, but they did wrong themselves; and their gods on whom they call beside Allah availed them naught when came thy Lord's command; they added to them naught save ruin.
