وَأَصْفَرَ مَضْبُوحٍ نَظَرْتُ حِوَارَهُ
عَلَى النَّارِ وَاسْتَوْدَعْتُهُ كَفَّ مُجْمِدِ
Meaning: The poet recalls a yellow gaming shaft, heated and treated by the fire, whose outcome he watched before entrusting it to a man regarded as unsuccessful or unlucky in the game.
Aṣfar describes its yellow color; maḍbūḥ points to treatment by heat; the underlying qadaḥ is a shaft used in the old Arabian drawing or gambling game of maysir, not a drinking cup in this context. The scene depicts a historical practice.
