«فَفَصَلْتُ عَنْهُ بِكَبِدٍ مَرْضُوضَةٍ وَدُمُوعٍ مَفْضُوضَةٍ»
So I departed from him with a bruised heart and tears flowing freely.
Kabid marḍūḍa makes inner anguish a wounded liver or heart; dumūʿ mafḍūḍa pictures tears being released. The similar endings of marḍūḍa / mafḍūḍa give the prose a rhyming cadence.
The passage should be read for its emotional force, but the tears are still part of the character’s account, not independent corroboration of his alleged kinship.
