Ruling on one who prayed while part of her hair was exposed

Question:
We return at the beginning of this episode to the letter from the listener (M. M. M.) from Riyadh. We presented some of his questions in a previous episode, and in this episode he asks Your Eminence, Shaykh Abdul Aziz, saying: If I am praying, and after I finish the prayer, for example the Zuhr prayer, I discover that part of my hair was exposed—this question appears to be from a woman, Your Eminence—do I repeat the prayer, or do I repeat the last two rak'ahs during which I discovered that my hair was exposed? May Allah reward you with good.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, and may Allah send prayers and blessings upon the Messenger of Allah, and upon his family and his Companions, and upon those who follow his guidance. As for what follows:
This matter requires detail: If the exposed part was small, and you did not become aware of it until after the prayer, then there is no blame on you, and the prayer is valid. However, if the exposed part was large, the safest course for you is to repeat the prayer. Yes.
