What is the ruling on wearing short sleeves in the presence of mahrams?

Question : The questioner says: Regarding wearing short sleeves for women in the presence of mahrams, O Shaykh?

Answer : In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds. May Allah send prayers and blessings upon our Prophet Muhammad, his family, his Companions, and those who follow them in excellence until the Day of Judgment.
I say that the looser the woman’s garment, the better it is, and women should not be expansive in this matter. I fear that if I say there is no harm in a woman exposing her arm to her mahrams and her sisters, the woman will remain in that state for a while, then move to exposing her upper arm, then her shoulder, and then limit herself to her two breasts. There is no limit for women if you open the door for them.
Therefore, what a woman should do is have her sleeves extend to the wrist, whether in the presence of women or in the presence of mahrams; this is the best and the safest. As for the issue of specification, yes, there is no harm in exposing the forearm in front of women and in front of mahrams.
