Blood came out of her nose onto her khimar (head covering) and she completed five obligatory prayers; is her prayer valid?

The questioner : Peace be upon you. And upon you be peace. A question from a traveler. What is the question? She says: Blood came out of her nose onto her khimar, O Shaykh, and she completed five obligatory prayers with it. Does she have to repeat these prayers, O Shaykh?

The Shaykh : No, she does not have to repeat them.

The questioner : Even if...

The Shaykh : Even if the blood was a lot, O Shaykh. Yes, even if the blood was a lot, but she washes it so that people do not feel disgusted by her.
