﴿ فَلَا تَكُ فِى مِرْيَةٍۢ مِّمَّا يَعْبُدُ هَٰٓؤُلَآءِ ۚ مَا يَعْبُدُونَ إِلَّا كَمَا يَعْبُدُ ءَابَآؤُهُم مِّن قَبْلُ ۚ وَإِنَّا لَمُوَفُّوهُمْ نَصِيبَهُمْ غَيْرَ مَنقُوصٍۢ ﴾

“AND SO, [O Prophet,] be not in doubt about anything that those [misguided people] worship: they but [thoughtlessly] worship as their forefathers worshipped aforetime; and, behold, We shall most certainly give them their full due [for whatever good or evil they have earned], without diminishing aught thereof.”
