وَإِنْ يَقْذِفُوا بِالْقَذْعِ عِرْضَكَ أَسْقِهِمْ
بِكَأْسِ حِيَاضِ الْمَوْتِ قَبْلَ التَّهَدُّدِ
Meaning: If opponents insult your honor with abusive words, I would make them drink from the cups of death’s pools even before threats were exchanged.
Al-qadhʿ is obscene or abusive speech, al-ʿirḍ one’s honor, and ḥiyāḍ al-mawt literally “the pools of death.” Asqihim bi-kaʾs turns the language of offering a drink into an image of violent retaliation. This belongs to the hyperbolic rhetoric of pre-Islamic tribal boasting, not to a present-day prescription for conduct.
