«إِنَّمَا يَتَذَكَّرُ أُولُو الْأَلْبَابِ»
Only people of understanding take heed.
In context this says more than the bare fact that thoughtful people heed reminders. Addressed to those who refuse correction, it can imply indirect criticism (تعريض) of their conduct without explicitly naming them.
By highlighting the positive trait of one group, innamā can indirectly expose the failure of an opposing attitude. This suggested criticism does not replace the literal construction: first identify the restricted predication, then explain any additional implication supplied by context.
