Is it forbidden for a woman to express her opinion or to always submit to a man's opinion? And is her criticism and holding men accountable considered a violation of Sharia?

A woman is permitted to express her opinion and offer advice, as there is ample evidence supporting this. Examples include Umm Salama's advice to the Prophet, peace and blessings be upon him, during the Treaty of Hudaybiyyah. Furthermore, Bilqis is mentioned in the Quran as a model of a woman possessing wisdom and sound judgment. In addition, the Prophet's Sunnah indicates the permissibility of consulting women, discussing matters with them, and seeking their arguments. A man should listen to a woman if she is correct. As for the narrations that suggest it is not permissible to accept a woman's opinion or that women should oppose men, these are weak and rejected reports.
