وَقَوْلُ الْقَائِلِ: «إِنَّمَا يَعْرِفُ ذَا الْفَضْلِ مِنَ النَّاسِ ذَوُوهُ» شَاذٌّ.
Translation: The verse “Only those close to a person of merit recognize that merit among people” is classified by the author as exceptional (shādhdh).
ذَوُوهُ demonstrates annexation to a pronoun, but the author calls it irregular/exceptional. It should not override the standard rule.
