The ruling on a person passing in front of the one praying and its effect on the prayer

Question:
A woman from the program, who used the code name "Alf Alf Riyadh," asks: Does the prayer become invalid if a person, male or female, small or large, passes in front of the one praying, even if he has placed a barrier such as a pillar, a chair, or a stick? And does their passing invalidate the prayer?

Answer:
If he places a sutrah in front of him and a person passes behind it, then this has no effect. But if he does not place a sutrah and a person passes close to him or between him and his sutrah, then this is a forbidden matter. It is not permissible for a person to pass, and it is not permissible for the one praying to allow him to pass. But does the prayer become invalid because of that?
As for a man, his passing in front of the one praying does not invalidate the prayer, but he will be like a fire, and the one praying should fight him if he can. The Prophet (peace and blessings be upon him) said: , and the Prophet (peace and blessings be upon him) ordered that the fire be prevented from passing in front of him. He said: meaning the devil. As for a man passing in front of the one praying, close to him or between him and his sutrah, without necessity, this is forbidden and it is a transgression, but it does not invalidate the prayer. As for a woman passing in front, this is a matter of disagreement among the scholars. Some scholars hold that it invalidates the prayer and cuts it off, while others hold that the prayer is not invalidated, but it is a transgression.
