قالوا اقترح شيئاً نجد لك طبخه
They said: Suggest something that we can cook for you.
The poet replies in effect, “Cook me a gown and a shirt.” The first ṭabkh is literal food preparation, whereas when applied to clothing it signifies making the garments, not putting them into a cooking pot.
The second verb adopts the form of the first through actual conversational companionship. This is mushākalah, and the humor depends on understanding that identical wording denotes different activities.
