«فَدَخَلَ ذُو لِحْيَةٍ كَثَّةٍ وَهَيْئَةٍ رَثَّةٍ»
A man entered with a thick beard and a shabby appearance.
Liḥyah kaththah is a thick beard, and hayʾah raththah describes a worn or shabby bearing. The near-rhyme makes his first appearance particularly memorable.
His status is not identified. The contrast to watch is between the unpromising exterior and the eloquence that soon becomes evident.
