Question: Is it permissible for a sister to appear in front of her brother – revealing her lower legs [from below the knee] and arms?
Response: It is not permissible for a woman to display [anything] in front of her mahrams and [other] muslim women other than the [well known] areas of [her] beauty; Amongst them [that which] Allaah (Subhaanahu wa Ta’aala) said:
And the [well known] areas of beauty are:
The hand and [the neck area] where the necklace is worn, and [the wrist area] where the bracelet is worn, and the upper arm where the bangle is worn, and likewise the feet, and [the ankle area] where the anklet is worn.
So these are the only areas which are permissible for a woman to display in front of her mahrams and [other Muslim] women.
