سَيَقُولُونَ ثَلَٰثَةٞ رَّابِعُهُمۡ كَلۡبُهُمۡ وَيَقُولُونَ خَمۡسَةٞ سَادِسُهُمۡ كَلۡبُهُمۡ رَجۡمَۢا بِٱلۡغَيۡبِۖ وَيَقُولُونَ سَبۡعَةٞ وَثَامِنُهُمۡ كَلۡبُهُمۡۚ قُل رَّبِّيٓ أَعۡلَمُ بِعِدَّتِهِم مَّا يَعۡلَمُهُمۡ إِلَّا قَلِيلٞۗ فَلَا تُمَارِ فِيهِمۡ إِلَّا مِرَآءٗ ظَٰهِرٗا وَلَا تَسۡتَفۡتِ فِيهِم مِّنۡهُمۡ أَحَدٗا
