I fear for my wife from the evil and harms of the internet, so what is your advice to me and to her in this?

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: I am in a dispute with my wife over the internet and its use. I am in a dispute with my wife over the internet and its use, so I fear for her from its evil and harms. She wants to use it to communicate with her female colleagues, and she says that by preventing her from it, I do not trust her. What is your advice to me and to her in this?

Answer:
Prevent her from it. You are the one in authority over her, and you are responsible for her. The house is your house, so prevent her from this, and do not be soft with her in this matter; because this is a means through which you reach out and evil occurs and tribulation occurs, with women and with girls. This is a means of evil, so prevent her from it. You have authority over her, .
