Surat Hud (Hud) - هود

فَلَا تَكُ فِى مِرْيَةٍ مِّمَّا يَعْبُدُ هَٰٓؤُلَآءِ مَا يَعْبُدُونَ إِلَّا كَمَا يَعْبُدُ ءَابَآؤُهُم مِّن قَبْلُ وَإِنَّا لَمُوَفُّوهُمْ نَصِيبَهُمْ غَيْرَ مَنقُوصٍ ﴿١٠٩﴾

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.
