Is the intended meaning of a woman interrupting the prayer its invalidation or a reduction in the reward?

Question:
He says: Honorable Shaykh, may Allah grant you success, does a woman interrupting the prayer by passing in front of the one praying mean that the prayer is invalidated, or is it merely a reduction in the reward?

Answer:
The majority hold that it does not invalidate the prayer, but the reward is reduced. A group of distinguished scholars, such as Imam Ahmad and others, say that it is invalidated by a woman, a black, ugly dog, or a donkey, as stated in the hadith. It is neither invalidated nor valid, according to the apparent meaning of the hadith. Allah knows best. Yes.
