فَآلَيْتُ لَا يَنْفَكُّ كَشْحِي بِطَانَةً / لِعَضْبٍ رَقِيقِ الشَّفْرَتَيْنِ مُهَنَّدِ
I have sworn that my side shall never be parted from a keen Indian sword with fine, sharp edges.
Fa-ālaytu means “I swore an oath.” Lā yanfakku expresses continued inseparability. Kashḥī is the flank or side, and biṭānah conveys close attachment.
The speaker boasts that a sword remains constantly at his side. ʿAḍb (keen blade), raqīq al-shafratayn (fine-edged), and muhannad (Indian-made or Indian-style sword) jointly stress the weapon’s cutting quality.
