ولئن نطقت بشكر برك مفصحاً، فلسان حالي بالشكاية أنطق
Though I speak clearly in gratitude for your kindness, the tongue of my condition speaks still more strongly in complaint.
In the expression “the tongue of my condition,” the condition is mentally treated as something capable of speaking. A condition possesses no anatomical tongue, but its outward signs may communicate an inward state.
The attributed “tongue” invites the listener to imagine the condition as a speaker. The point is not physical anatomy; it is the silent but compelling testimony of circumstances, contrasted with spoken thanks.
