وَأَوَدُّ الْحَمِيمَ وَلَوْ جَرَّعَنِي الْحَمِيمَ
I cherish a close friend even if he makes me swallow, as it were, scalding water.
The first ḥamīm means a close friend; the second, scalding liquid. The exact repetition under different senses makes the wordplay memorable and gives the vow of loyalty an edge.
Jarraʿanī suggests being made to swallow in painful draughts. Its verb context selects the “hot water” meaning for the second instance. Meaning is decided by grammar and collocation, not by spelling alone.
