Al Kahf Ayah 22

سَيَقُولُونَ ثَلَـٰثَةٌ رَّابِعُهُمْ كَلْبُهُمْ وَيَقُولُونَ خَمْسَةٌ سَادِسُهُمْ كَلْبُهُمْ رَجْمَۢا بِٱلْغَيْبِ‌ۖ وَيَقُولُونَ سَبْعَةٌ وَثَامِنُهُمْ كَلْبُهُمْ‌ۚ قُل رَّبِّىٓ أَعْلَمُ بِعِدَّتِهِم مَّا يَعْلَمُهُمْ إِلَّا قَلِيلٌ‌ۗ فَلَا تُمَارِ فِيهِمْ إِلَّا مِرَآءً ظَـٰهِرًا وَلَا تَسْتَفْتِ فِيهِم مِّنْهُمْ أَحَدًا ٢٢ Some will say, “They were three, their dog was the fourth,” while others will say, “They were five, their dog was the sixth,” ?only? guessing blindly. And others will say, “They were seven and their dog was the eighth.” Say, ?O Prophet,? “My Lord knows best their ?exact? number. Only a few people know as well.” So do not argue about them except with sure knowledge, nor consult any of those ?who debate? about them.
