Quran 11:109 Hud, ayah 109 of 123

فَلَا تَكُ فِى مِرْيَةٍ مِّمَّا يَعْبُدُ هَـٰٓؤُلَآءِ ۚ مَا يَعْبُدُونَ إِلَّا كَمَا يَعْبُدُ ءَابَآؤُهُم مِّن قَبْلُ ۚ وَإِنَّا لَمُوَفُّوهُمْ نَصِيبَهُمْ غَيْرَ مَنقُوصٍ ۝١٠٩

11:109 So be not thou in doubt concerning that which these (folk) worship. They worship only as their fathers worshipped aforetime. Lo! we shall pay them their whole due unabated.
