«لِلَّهِ دَرُّكَ فَمَا أَعْذَبَ نَفَثَاتِ فِيكَ! وَاهًا لَكَ لَوْلَا خِدَاعٌ فِيكَ!»
How sweet your eloquence is—if only it were free from deceit!
The judge first admires the sweetness of expression and then inserts an ethical reservation through “were it not for deceit.” The turn changes the value of the praise without denying the skill.
This is an important distinction between aesthetic excellence and moral conduct. The rhetorical force comes from bringing the two assessments together rather than collapsing them into one.
