All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
Islam teaches that Zina is a major sin. A child must advise the parent to repent and stop, but if they persist, the other spouse should be informed. Remaining silent makes one complicit in sin, while sincere repentance opens the door to Allah’s forgiveness.

Responding to your question, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states:
You need to do everything within your means to stop your mother; if she doesn’t stop her most heinous deed, you should tell your father. By condoning her vicious action, you become a partner in sin. She should worry about her fate rather than worrying about your fate in the hereafter.
Adultery is one of the major sins in Islam. Please remind her about the gravity of the sin she is committing. Here are some quotes from the Quran and Hadith:
Allah says in the Quran, {Do not even go near adultery for it is, for it is an indecent thing and an evil way.} (Al-Isra 17:32)
{(And the servants of the Beneficent) are those who do not upon another god with Allah, and who do not…….commit fornication/adultery, for whoever does that shall receive the penalty; for him/her shall the torment be doubled on the day of resurrection, and therein he/she shall abide forever, disgraced, save him/her who repents and believes, and does good works; those, Allah shall change their misdeeds into good works. And Allah is Forgiving, Compassionate.} (Al-Furqan 25:68-70)
The Prophet (peace be upon him) said, “Whoever guarantees me that he/she will guard his/her chastity, I will guarantee him/her paradise.” (Reported by Al-Bukhari)
Abu Hurayrah (may Allah be pleased with him) reports that the Messenger of Allah said, “No one commits adultery while remaining a believer, for faith is more precious unto Allah than such an evil act!”; in another version, it is stated, “When a person commits adultery they cast away from their neck the bond that ties him to Islam; if, however, they repent, Allah will accept their repentance.” (Reported by Al-Bukhari, Muslim, Abu Dawud, An-Nasa’i and others)
