(Al-Muaminoon) 23 : 68
أَفَلَمْ يَدَّبَّرُوا الْقَوْلَ أَمْ جَاءَهُمْ مَا لَمْ يَأْتِ آبَاءَهُمُ الْأَوَّلِينَ

Then why don’t they think and become proud upon this Word, or has there come to them that which hadn’t come to their forefathers?

The Fujjar who have made their food ‘rejecting Adhikr’ are proud of the Arabic body of the Book. They are falsely claiming before mankind that they are Muslims. But these true disbelievers mentioned in verses 4: 150-151 are serving Satan and are following his footsteps. See explanation 3: 79-80; 4: 82 and 9: 115.
