What is the ruling on passing wind involuntarily for a woman performing 'Umrah or prayer, despite her attempts to suppress it, and is she required to repeat previous 'Umrahs or offer expiation?

If the emission of wind is continuous for a worshipper or one performing circumambulation (Tawaf), then they are in the ruling of a person afflicted with perpetual ritual impurity (sahib al-salas). They should purify themselves after the time for prayer begins and when performing Tawaf, and what is emitted thereafter does not harm them. Therefore, the past 'Umrahs are valid if their conditions for validity were met, and no expiation (fidyah) is due from them on account of the continuous emission.
