«وَخَوَّانٌ مِنَ الْإِخْوَانِ قَالَ لِي لِإِقْلَالِي»
One treacherous man among the brethren reproached me for my poverty.
Khawwān conveys habitual or pronounced treachery; ikhwān refers to brothers or close companions. The harshness comes from treachery within a circle of trust. “A brother was unhappy” would soften the complaint beyond recognition.
The phrase “because of my poverty” identifies the occasion of the alleged betrayal. Since this complaint is part of a public appeal for alms, it should be translated as the speaker's allegation, not independently verified fact.
