She is asking about a specific du’aa’ for when she finishes her period

There is a similar question on this site, but it is not exactly what I need. I was wondering if, when a lady needs to purify herself from the menses, how should she, and is there a special dua she needs to make?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

If the bleeding stops and she become pure, and she does ghusl after menstruation with the intention of purifying herself, then she is considered to be pure (taahirah). There is no specific du’aa’ for that, apart from the well known du’aa’s that have been narrated for doing wudoo’. And Allah knows best.
