Ruling on passing in front of a person praying without a barrier

Question:
What is the ruling on someone who passes by while the person praying is praying at a distance of three meters, knowing that there is no barrier between him and the person praying?

Answer:
The person praying is the one who was negligent, so he owes nothing, but he should not get close to him; he should pass by at a distance. The Prophet (peace and blessings be upon him) prayed in the Ka'bah at a distance of three cubits, with three cubits between him and the wall. So if he is far from him, with three cubits or more between him and the person praying, it does not harm him. But if there is a barrier, he should not pass between him and it; he should pass behind it.
