وَتَرْوِي رِوَايَتُهُ غُلَّتِي
And his narration would quench my thirst.
Tarwī means “to give drink or satisfy thirst.” Riwāyatuhu is his narration, while ghullah denotes intense thirst.
This is not merely physical thirst. The narrator's longing for literary companionship is pictured as something satisfied by refreshing words.
