وَإِذَا ظُلِمْتُ فَإِنَّ ظُلْمِي بَاسِلٌ مُرٌّ مَذَاقَتُهُ كَطَعْمِ الْعَلْقَمِ
But if I am wronged, my retaliation is harsh, with a taste as bitter as colocynth.
Bāsil means formidable or severe, and al-ʿalqam is a markedly bitter plant or fruit (colocynth). Murrun madhāqatuhu makes retaliation something tasted. The sensory comparison expresses severity through bitterness; it is a claim within a boast poem, not legal or moral instruction.
