أَبِيتُ الْوِصَالَ مَخَافَةَ الرُّقَبَاءِ، وَأَنْتَ تَحْتَ مَدَارِعِ الظُّلَمَاءِ

Normally a pronoun is interpreted through an identifiable antecedent. The source discusses cases where a pronoun is given prominence before its referent has been plainly supplied, encouraging attention or expectation.
Preceding the overt referent is not automatically eloquent. Context must still make the relation intelligible, or the result is ambiguity rather than a deliberate rhetorical effect.
