1742/1 - Ibn Mas‘ūd (may Allah be pleased with him) reported that the Prophet (may Allah’s peace and blessings be upon him) said: “No woman should look at another woman and then describe her to her husband as if he is looking at her.” [Narrated by Al-Bukhāri and Muslim]
--
1) It is not permissible to describe a woman to a foreign man. This is to block the means leading to immorality among people.
2) The Shariah prohibits the woman from describing another woman to her husband, for this could ruin their marital life. It also exposes people’s private aspects and stirs up discord among them.
