Is it considered a sin to remove the niqab after wearing it due to feeling distressed and fearing harm, especially with a child requiring care and household duties, in addition to the increasing cases of assault on women who wear the niqab?

Covering a woman's face is obligatory according to the soundest opinion, and this is the madhhab of Imam Ahmad, the soundest opinion within the Shafi'i madhhab, and the madhhab of the Hanafis and Malikis if times become corrupt. This is based on the Almighty's saying: "And when you ask [his wives] for anything, ask them from behind a partition. That is purer for your hearts and their hearts," and based on Aisha's, may Allah be pleased with her, statement during the incident of the Slander (Al-Ifk): "So I covered my face with my jilbab."

Discomfort, heat, prolonged hospitality, childcare, or cooking are not considered excuses for abandoning the niqab. Such conditions existed during the time of the Prophet. If a tightly-worn niqab causes difficulty in breathing, it can be replaced with another covering that hangs over the face without being tightly bound.

The husband should understand his wife's excuse for not accompanying him and provide suitable conditions for her, such as allocating a room for women or preventing his brothers from entering common areas in the house. This is based on the Prophet's (peace be upon him) saying: "Beware of entering upon women," and his saying about the husband's in-laws: "The in-laws are death."

As for fearing harm due to the niqab, if the harm is merely verbal abuse and mockery, it is not permissible to abandon it. However, if harm materializes as assault or beating, it is permissible to abandon it for the duration of the fear, then return to it once safety is secured. One must consult scholars in their country to assess the extent to which harm has materialized.
