(Az-Zukhuruf) 43 : 52
أَمْ أَنَا خَيْرٌ مِنْ هَٰذَا الَّذِي هُوَ مَهِينٌ وَلَا يَكَادُ يُبِينُ

“Am I not better than this one who is despicable and lacks eloquence in speech?”

The Arabic Quran-reading Fujjar, who do not utilize their intelligence to understand the aim of life, are serving Satan and following his footsteps as explained in verses 2: 168-169 and 36: 59-62. They are the original disbelievers, and for them, heinous punishment is kept prepared as explained in verses 4: 150-151. See explanation 20: 24-28; 38: 24; and 43: 18.
