«جَادَ بِالْعَيْنِ حِينَ أَعْمَى هَوَاهُ عَيْنَهُ فَأَتَانِي بِلَا عَيْنَيْنِ»
Desire blinded his eye; he parted with cash and was left as though sightless.
The repeated root supports several meanings: ready cash, the eye, and two eyes. The shifts are intelligible only by reading each occurrence within its own phrase.
The pun makes the patron’s payment an emblem of impaired judgement. Economic loss and figurative blindness become intertwined without the claim that the man literally lost his eyes.
