The ruling on obeying one’s mother in leaving the Fajr prayer in congregation due to her extreme fear

Question : A young man’s mother orders him not to go out for the Fajr prayer. If there is no one else among his brothers to go, because of her extreme fear, should he obey her and pray at home, or disobey her, or go out secretly while being mindful of her feelings about it?

Answer : It is obligatory for him to pray with the congregation, and it is not permissible for him to obey his mother in leaving the congregation. However, he should conceal it from her and hide it from her if possible.
