A relative clause can produce veneration (تعظيم) or awe (تهويل). In the first, it foregrounds a person's stature or merit. In the second, it presents the magnitude or gravity of an event. Both go beyond simple naming by shaping the hearer's response.
Contrasting teaching examples:
«الذي أنقذ الناس من الغرق حاضر» — The one who saved people from drowning is present: respect for a remarkable deed.
«الذي زلزل المدينة وقع ليلاً» — The event that shook the city happened at night: attention to magnitude.
These examples illustrate rhetorical potential. The actual effect depends on audience and context; descriptive detail alone does not dictate a single response.
