Qualification can also serve blame or disparagement (dhamm), emphasizing an unfavorable characteristic of someone already identified.
جَاءَنِي زَيْدٌ الْجَاهِلُ
Zayd, the ignorant one, came to me.
If the hearer knows Zayd, the adjective may criticize his lack of learning or his conduct. Where two men named Zayd are distinguished by contrasting attributes, it may instead primarily identify one of them. Blame and identification are contextual functions.
