The ruling on passing in front of the one praying

Question:
The questioner says: Regarding passing in front of a person praying, does it invalidate the prayer? And do I have to repeat what I prayed?

Answer:
The prayer is not invalidated, but there is sin in doing so if there is no dire necessity for passing. If there is a dire necessity for passing, such as in mosques crowded with people, there is no harm in passing. Or if you are praying behind the imam, the imam’s barrier serves as a barrier for those behind him; the imam’s barrier serves as a barrier for those behind him. Or if the passerby goes behind your barrier, and you have a barrier in front of you and the passerby goes behind it, that also does no harm. However, if the passerby goes between you and your barrier and there is no dire necessity for passing, then you sin if you let him pass, and he sins. If the passerby knows that he is passing in front of a person praying, what is required of him?
It would be better for him to stand for forty [paces] than to pass in front of him. The Prophet (peace and blessings be upon him) ordered that he be fought if he refused and did not refrain from passing, and that the one praying should prevent the passerby from passing in front of him. If he refuses to refrain, let him fight him, meaning strike him. The intended meaning of fighting is striking until he refrains from this. Yes.
