Question: Does the women cut the prayer of woman if she passes before her (in front of her)?
Answer: Yes, she does, because there is no difference in the legislations for the man and women except with evidence. But if she passes behind the shutrah if there was a shutrah, or behind her (prayer) rug if she was praying on a (prayer) rug or behind the place of her prostration, even though she didn't have a shutrah nor a (prayer) rug, then she does not harm and (prayer) is not wiped away (prayer is not cut/invalidated).
