The Holy Qur'an explicitly prescribes special instructions for the wives of the Prophet and has special strictness towards them. Islam wanted the "mother of the believers", who inevitably had a lot of respect among Muslims, not to abuse their respect and not to be "tools of selfish and adventurous elements in political and social issues."
In our opinion, this is the secret that the wives of the Prophet were forbidden to marry another person after that; That is, the next husband abused his wife's fame and respect and created adventures.
But how can a woman who is divorced from the Prophet be considered the mother of the believers while she is not the wife of the Prophet? She is divorced and can marry any other man.
Therefore, a woman who is separated from the Prophet is no longer the mother of the believers, and the rulings and honors imposed on the wives of the Prophet do not apply to her. He wants a woman after divorce like other Muslim women.
