Is it obligatory for a Muslim woman to wear a skirt over her trousers when performing prayer? What should she do if she is outdoors? Does she perform prayer without the skirt or should she carry one with her?

All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

It is permissible for a woman to perform prayer wearing loose-fitting trousers that do not outline or define the shape of her body. If the trousers are tight-fitting, then it is disliked to perform prayer in them if she is performing the prayer away from non-Mahram men. It is recommended for her to wear a long shirt or the like over the trousers. However, if she is seen by non-Mahram men, then it is impermissible for her to wear trousers or pray in them.

Allaah Knows best.
