Prohibition of Describing the Charms of a Woman to a man without a valid reason approved by the Shari'ah
Commentary: "Mubashirah'' means "meeting of two bodies'' and here it signifies that one should not see another person's body. Here, it is used in its literal as well as metaphorical sense. What it really means is that neither a woman should see the body of any other woman nor should she touch her own body with the body of some other woman, for if she does so, she will come to know the physical qualities of the other woman which she may disclose to her husband. Such disclosures may induce her husband to mischief and eventually ruin her own life. One is allowed, however, to disclose a woman's charms to a man who intends to marry her.
It is prohibited for a woman to describe another woman to her husband.
The Messenger of Allah (peace be upon him) said: "...and she describes her to her husband as if he were looking at her. " [Bukhari]
This type of description has many dangers; among them is that love for the other woman might enter the husband's heart, and so he starts wishing that he was with the other woman that is described to him, instead.
Tafir Ibn Kazir: Surah an-Noor(and not to reveal their adornment except to their husbands, or their fathers, or their husband's fathers...), "The paternal uncle and maternal uncle are not mentioned here, because they may describe a woman to their sons, so a woman should not remove her Khimar in front of her paternal or maternal uncle.''With regard to the husband, all of this is for his sake, so she should try her best when adorning herself for him, unlike the way she should appear in front of others.
(or their women,) this means that she may also wear her adornment in front of other Muslim women, but not in front of the women of Ahl Adh-Dhimmah (Jewish and Christian women), lest they describe her to their husbands. This is prohibited for all women, but more so in the case of the women of Ahl Adh-Dhimmah, because there is nothing to prevent them from doing that, but Muslim women know that it is unlawful and so, would be deterred from doing it. The Messenger of Allah said:
(No woman should describe another woman to her husband so that it is as if he is looking at her.) It was recorded in the Two Sahihs from Ibn Mas`ud.
