الَّذِينَ هُمْ يُرَاءُونَ
those who act for display. (107:6)
Repeating alladhīna introduces another attribute of the condemned group. Hum is the nominal subject and the verbal clause yurāʾūn functions as its predicate. The construction foregrounds both the people and their characteristic action.
The verse condemns showing off in worship. Merely doing good in public does not in itself prove an insincere intention; the rhetorical description is not a license to infer a specific person’s hidden motives without evidence.
