If you find out that someone saw some of your hair during your prayer, do you complete your prayer or repeat it?

The questioner:
May Allah reward you with good, and may He do you good. If you find out that someone saw some of your hair during your prayer, do you complete your prayer or repeat it?

The Shaykh:
If some of a woman’s hair is exposed during her prayer, and it happens without her intention, if it is exposed without her intention

The questioner:
Yes, yes.

The Shaykh:
and she hastens to cover it, then her prayer is valid. However, if she exposes it intentionally, or if it is exposed without her intention and she knows about it and leaves it exposed, then her prayer is invalid, because she has left one of the conditions of prayer, which is covering the 'awrah (the part of the body that must be covered). The entire body of a woman is 'awrah in prayer, except her face, if there are no non-mahram (relatives one may not marry) men present with her. Yes.
