«لَا تَلَمَّظْتُ بِقِرَاكُمْ»
I shall not savour your hospitality with lip-smacking delight.
Qirā means the meal or provisions offered to a guest. Talammaẓ evokes licking one’s lips in anticipation or enjoyment. The guest is not condemning food; he makes his willingness to eat depend on a promise from his hosts.
This vivid physical image keeps the discussion of courtesy lively instead of reducing it to an abstract instruction.
