«لَقَدِ اسْتَسْمَنْتَ يَا هَذَا ذَا وَرَمٍ»
You have mistaken a swollen person for someone well-fed!
Istasmanta means “you took someone to be fat,” whereas waram means a swelling. The two may resemble each other visually, though their causes and values differ.
The speaker uses this contrast as a cutting analogy: attractive appearance is not always evidence of genuine excellence.
«وَنَفَخْتَ فِي غَيْرِ ضَرَمٍ»
You blew where no flame was burning.
Together the analogies criticise praise without adequate substance.
