فَلَا تَكُ فِى مِرْيَةٍ مِّمَّا يَعْبُدُ هَـٰٓؤُلَآءِ ۚ مَا يَعْبُدُونَ إِلَّا كَمَا يَعْبُدُ ءَابَآؤُهُم مِّن قَبْلُ ۚ وَإِنَّا لَمُوَفُّوهُمْ نَصِيبَهُمْ غَيْرَ مَنقُوصٍ
So do not be in doubt about what these worship: they worship just as their fathers worshiped before, and We shall surely pay them their full share, undiminished.
