Hud 11:109

Fala taku fee miryatin mimmayaAAbudu haola-i ma yaAAbudoona illakama yaAAbudu abaohum min qablu wa-innalamuwaffoohum naseebahum ghayra manqoos

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.

So, be not in doubt about what they worship. They worship only in the way their fathers used to worship earlier. Surely, We are going to pay them their full share, not curtailed in the least.
