Multiple rhetorical devices may be recognized when separate features of an utterance meet separate technical conditions. In “sāʾil al-laʾīm … wa-damʿuhu sāʾil”, the repeated form with distinct senses provides one argument, while its beginning-and-end position provides another. Multiplying labels from one unspecific impression is not rigorous analysis.
Use a compact template: cite the text; identify the relevant words or meanings; state each device's condition separately; reject one plausible but incorrect alternative; and explain the combined effect.
Two defensible classifications are more valuable than eight labels lacking a verifiable basis in the passage.
