جَادَتْ لَهُ كَفِّي بِعَاجِلِ طَعْنَةٍ بِمُثَقَّفٍ صَدْقِ الْكُعُوبِ مُقَوَّمِ
My hand dealt him an immediate thrust with a well-straightened, sturdy spear of sound joints.
Jādat lahu kaffī transfers a verb of generous giving into a violent encounter, producing sharp irony. Muthaqqaf refers to a straightened shaft; ṣidq al-kuʿūb stresses the soundness of its joints.
