It is narrated from Sayyidah Aishah (may Allah be pleased with her) that she married Hafsah bint Abd al-Rahman to al-Mundhir bin al-Zubayr while Abd al-Rahman was away in Syria. When Abd al-Rahman arrived, he said: Is this done to someone like me, and is the matter decided without me? So Sayyidah Aishah (may Allah be pleased with her) spoke to al-Mundhir bin al-Zubayr, and al-Mundhir said: This matter is in the hands of Abd al-Rahman. Abd al-Rahman said: I will not reject a matter that you have decided. So Hafsah remained with al-Mundhir, and this was not a divorce. What is meant by this is that Sayyidah Aishah (may Allah be pleased with her) gave guidance for the marriage; then someone else conducted the marriage contract, so the marrying was attributed to her because of this permission and guidance. And Allah knows best.
