فَلَا تَكُ فِى مِرْيَةٍ مِّمَّا يَعْبُدُ هَٰٓؤُلَآءِ مَا يَعْبُدُونَ إِلَّا كَمَا يَعْبُدُ ءَابَآؤُهُم مِّن قَبْلُ وَإِنَّا لَمُوَفُّوهُمْ نَصِيبَهُمْ غَيْرَ مَنقُوصٍ
So do not be in doubt, [O Muhammad], as to what these [polytheists] are worshipping. They worship not except as their fathers worshipped before. And indeed, We will give them their share undiminished.
