All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Dear brother, you are responsible for your wife and your children and you will be asked about them on the Day of Judgment. It is confirmed that the Prophet said: “Every one of you is a guardian and is responsible for the people under his guardianship: the Imam (Muslim ruler) is a guardian and is responsible for the people under his guardianship, a man is a guardian in his house and is responsible for the people under his guardianship, and a woman is a guardian in her husband’s home and she will be questioned over the people under her guardianship.” [Al-Bukhari and Muslim]
Therefore, if you are certain of what you said about your wife, then you must talk to her about this matter and show her a real proof for what you mentioned. You should scold her about this but with wisdom and good preaching. This is part of the conditions of being the guardian in your family, i.e., the responsibility which Allah has put upon your shoulder. It is also one of the reasons of protecting her from Hellfire; Allah Says (what means): {O you who have believed, protect yourselves and your families from a Fire whose fuel is people and stones, over which are [appointed] angels, harsh and severe; they do not disobey Allah in what He commands them but do what they are commanded.} [Quran 66:6]
Keeping quiet and silent over this matter makes you a cuckold and this is a very serious matter. It is confirmed that the Prophet said: “There are three kinds of people upon whom Allah has forbidden Paradise: an alcohol addict, a person who severs ties with his parents, and the cuckold who approves vicious acts done by his wife.” [Ahmad]
Allah knows best.
