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.
The Saheeh International Quran Translation
فَلَا تَكُ فِى مِرْيَةٍ مِّمَّا يَعْبُدُ هَٰٓؤُلَآءِ مَا يَعْبُدُونَ إِلَّا كَمَا يَعْبُدُ ءَابَآؤُهُم مِّن قَبْلُ وَإِنَّا لَمُوَفُّوهُمْ نَصِيبَهُمْ غَيْرَ مَنقُوصٍSo 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.
