Narrated 'Abdullah bin Mas'ud: The Prophet ﷺ said, "A woman should not look at or touch another woman to describe her to her husband in such a way as if he was actually looking at her".
This hadith also teaches us an important lesson about marriage - it is important for couples to trust each other and respect each other's privacy. If one partner does not feel comfortable with the way their spouse talks about someone else, then they need to communicate this with their partner so they can work together on finding a solution which works for both of them.
