فَطَعَنْتُهُ بِالرُّمْحِ ثُمَّ عَلَوْتُهُ بِمُهَنَّدٍ صَافِي الْحَدِيدَةِ مِخْذَمِ
I thrust at him with my spear, then struck him down with a keen Indian sword of fine steel.
Fa-ṭaʿantuhu ... thumma ʿalawtuhu orders two actions: a spear-thrust followed by a sword-strike. Muhannad denotes an Indian sword and mikhdham emphasises the capacity to cut decisively. The modifiers intensify the image of the weapon.
