Surah Hud, ayah 109

11:109

فَلَا تَكُ فِي مِرۡيَةٖ مِّمَّا يَعۡبُدُ هَٰٓؤُلَآءِۚ مَا يَعۡبُدُونَ إِلَّا كَمَا يَعۡبُدُ ءَابَآؤُهُم مِّن قَبۡلُۚ وَإِنَّا لَمُوَفُّوهُمۡ نَصِيبَهُمۡ غَيۡرَ مَنقُوصٖ ١٠٩

Falā taku fī miryatim mimmā ya'budu hā'ulā'i mā ya'budūna illā kamā ya'budu ābā'uhum min qablu wa innā lamuwaffūhum nasībahum ghayra manqūs

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.
