Is it permissible for this woman to interfere in issues between teachers and the administration, and to raise her voice under the pretext of demanding justice, despite her husband forbidding her and the teachers being capable of defending themselves?

Injustice is not removed by screaming and causing problems. Enjoining what is right and forbidding what is wrong should be done with gentleness, knowledge, and forbearance, and not by committing a wrong similar to the one being forbidden. It appears that this woman is not obligated to forbid what is wrong; in fact, it may be forbidden for her if her forbidding leads to a greater harm. She must obey her husband if he forbids her from doing so. Her statement, "Indeed, Allah has entrusted her with that," is a claim to the unseen and a fabrication against Allah, and she must repent from it. Allah Almighty said: "And do not say about what your tongues falsely describe – 'This is lawful and this is unlawful' – to invent falsehood against Allah. Indeed, those who invent falsehood against Allah will not succeed. A brief enjoyment, and for them is a painful punishment." As for her claim of knowing genealogy, there is no harm in it if she is known to be proficient in it; otherwise, it is not permissible for her to delve into people's lineages out of ignorance.
