The ruling on a sister staying overnight at the house of her married sister

Question:
If her sister is married, is it permissible for her to stay overnight at her sister's house?

Answer:
If she does not fear anything from her husband, meaning she does not fear fitnah (trial, discord or temptation), then there is no blame on her. If she does not fear fitnah, that is fine. However, if she does fear it, she should stay away, unless there is someone else with them, such as her mother, another sister, a servant, or something else that would remove the danger. But if she does not fear anything, then praise be to Allah.
