أتاني من أبي أنس وعيد / فسل لغيظة الضحاك جسمي
A threat reached me from Abū Anas, and my body seemed to melt at al-Ḍaḥḥāk’s fury.
The poetic line dramatizes a threat and an exaggerated physical response to supposed dread. Within an appropriate context, such overstatement can serve derision and irony rather than a literal acknowledgment that the addressee is truly terrifying.
Interpretation should avoid inventing the poem’s entire historical circumstances. The rhetorical technique itself is enough: the speaker ostensibly presents himself as frightened, but the force of exaggeration and context may convert this into a means of ridiculing the person issuing the threat.
