Does a man's prayer become invalid if a woman passes in front of him, or a dog passes, or is the reward merely diminished?

Question:
Honorable Shaykh, may Allah grant you success, he says: Does a man's prayer become invalid if a woman passes in front of him, or a dog passes, or is the reward merely diminished?

Answer:
It does not become invalid except if a black, dark-colored dog passes, one that has no color other than black. As for a woman passing, it does not cut off the prayer. The hadith means that the reward is cut off, not that the prayer is invalidated; the prayer does not become invalid. Yes.
