«عِنْدَ الِامْتِحَانِ يُكْرَمُ الرَّجُلُ أَوْ يُهَانُ»
At the time of testing, a person is honoured or humiliated.
This traditional saying moves the stranger's argument from protest to verification. A real poet will gain respect by performing; an impostor may expose his own weakness.
Yukram / yuhān are passive imperfect verbs. They form a balanced pair in sound but an opposition in meaning. The word aw presents two possible outcomes, making trial a fairer answer to doubt than an immediate verdict.
