فَلَا تَكُ فِى مِرْيَةٍ مِّمَّا يَعْبُدُ هَٰٓؤُلَآءِ ۚ مَا يَعْبُدُونَ إِلَّا كَمَا يَعْبُدُ ءَابَآؤُهُم مِّن قَبْلُ ۚ وَإِنَّا لَمُوَفُّوهُمْ نَصِيبَهُمْ غَيْرَ مَنقُوصٍ
Therefore be not in doubt as to what these worship; they do not worship but as their fathers worshipped before; and most surely We will pay them back in full their portion undiminished.
