يَا خَيْرَ مَنْ يَرْكَبُ الْمَطِيَّ وَلَا يَشْرَبُ كَأْسًا بِكَفِّ مَنْ بَخِلَا
O best of those who ride mounts, who does not drink a cup from a miser's hand.
The poetic style magnifies the praised person's excellence and generosity while suggesting another bearer of the same excellence drawn from him. The denial of drinking from a miser's hand functions as an indirect or allusive characterization.
The rhetoric goes beyond the direct claim “you are very generous.” Kināyah presents a quality through an accompanying indication, while tajrīd imagines a second bearer of the quality. Their combined effect must be distinguished analytically.
