Qur'an 11:109 · Hud

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

(109) So do not be in doubt, [O Muḥammad], 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.
