(El-Leblee.) Khufáf Ibn-Nudbeh Es-Sulamee says, [describing swords,]

جَلَاهَا الصَّيْقَلُونَ فَإَخْلَصُوهَا

خِفَافاً كُلُّهَا يَتْقِى بِأَثْرِ

[The furbishers polished them, and freed them from impurities, making them light: each of them preserving itself from the evil eye by means of its lustre]: i. e., each of them opposes to thee its فِرِنْد: (S, L:) يَتْقِىis a contraction of يَتَّقِى; and the meaning is, when a person looks at them, their bright rays meet his eye, so that he cannot continue to look at them. (L.)
