لَاهِيَةًۭ قُلُوبُهُمْ ۗ وَأَسَرُّوا۟ ٱلنَّجْوَى ٱلَّذِينَ ظَلَمُوا۟ هَلْ هَٰذَآ إِلَّا بَشَرٌۭ مِّثْلُكُمْ ۖ أَفَتَأْتُونَ ٱلسِّحْرَ وَأَنتُمْ تُبْصِرُونَ
With hearts preoccupied. And they confer in secret. The wrong-doers say: Is this other than a mortal like you? Will ye then succumb to magic when ye see (it)?
