وَقَدْ يُنَزَّلُ الْقَرِيبُ مَنْزِلَةَ الْبَعِيدِ
A nearby person may sometimes be treated as though distant.
A high-ranking addressee can be called with a form normally associated with distance, even when physically present. The distance is then not geographical but an indication of rank, awe, or elevated standing.
Choosing a distance-oriented particle to convey that stance is a rhetorical reassignment: treating the near as distant.
