فَلَا تَكُ فِيْ مِرْيَةٍ مِّمَّا يَعْبُدُ هٰٓؤُلَاۤءِ ۗمَا يَعْبُدُوْنَ اِلَّا كَمَا يَعْبُدُ اٰبَاۤؤُهُمْ مِّنْ قَبْلُ ۗوَاِنَّا لَمُوَفُّوْهُمْ نَصِيْبَهُمْ غَيْرَ مَنْقُوْصٍ ࣖ ( هود: ١٠٩ )
Falaa taku fee miryatim mimmmaa ya'budu haaa'ulaaa'; maa ya'budoona illaa kamaa ya'budu aabaaa'uhum min qabl; wa innaa lamuwaf foohum naseebahum ghaira manqoos (Hūd 11:109)
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. (Hud  : 109)

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.
