Surah Hud, Verse 109

فَلَا تَكُ فِي مِرۡيَةٖ مِّمَّا يَعۡبُدُ هَٰٓؤُلَآءِۚ مَا يَعۡبُدُونَ إِلَّا كَمَا يَعۡبُدُ ءَابَآؤُهُم مِّن قَبۡلُۚ وَإِنَّا لَمُوَفُّوهُمۡ نَصِيبَهُمۡ غَيۡرَ مَنقُوصٖ١٠٩

falā taku fī mir'yatin mimmā yaʿbudu hāulāi mā yaʿbudūna illā kamā yaʿbudu ābāuhum min qablu wa-innā lamuwaffūhum naṣībahum ghayra manqūṣin

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.
