«تَعَامَيْتُ حَتَّى قِيلَ إِنِّي أَخُو عَمًى»
I too pretended blindness until people said I was blind.
The second verse explains the ruse: taʿāmaytu states a deliberate pretence, while “brother of blindness” intensifies the apparent identity. The speaker can defend himself elegantly in verse, but rhetorical ingenuity does not itself establish the moral correctness of the deception.
