What is the validity of the prayer of one in front of whom a woman passes?

Question:
Do I have to repeat the prayer when a woman passes in front of me?

Answer:
This will come, if Allah wills, it will come. There is a prohibition against passing in front of the one praying, and it was mentioned in the hadith that it invalidates the beast.
The scholars differed on this issue with three opinions. Some say it is invalidated by the passing of the three, and it must be repeated, taking the apparent meaning of the hadith. Others say it is not invalidated by the passing of the three, but rather the meaning of invalidation here is the invalidation of the reward, not the invalidation of the prayer itself. That is to say, passing in front reduces the reward of the prayer, so the negation is of perfection, or the invalidation is of perfection, not of the reality and the original state.
The third opinion is the opinion of Imam Ahmad that it is not invalidated except by the passing of the black dog only, because it is a devil, as the Prophet (peace and blessings be upon him) said: "The black dog is a devil." The prayer is invalidated by its passing. Yes, and the issue is one of scholarly disagreement. But what appears, and Allah knows best, is that it is not invalidated absolutely, but rather the meaning is only the invalidation of the reward.
