Is the prayer of a Muslim woman invalidated when a non-Muslim woman enters upon her? Is her prayer valid or does she need to repeat it?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

The prayer of a Muslim woman is not invalidated when a non-Muslim woman enters upon her. The scholars did not consider that this invalidated prayer.
