«كريم متى أمدحه أمدحه والورى معي، وإذا ما لمته لمته وحدي»
He is generous: whenever I praise him, other people praise him with me; when I blame him, I do so alone.
The line repeats amdaḥuhu amdaḥuhu and lumtuhu lumtuhu in immediate succession. The commentary treats certain adjacent sound combinations as a source of difficulty in the utterance.
Even when repetition has an understandable rhetorical purpose, its phonetic smoothness must be evaluated separately. Repetition is not automatically a defect; the objection requires actual heaviness of pronunciation.
