Forms of Taking Back a Divorced Wife

The following message was received from a brother who used the initials (B. B) as a code for his name. He works in Abu Dhabi and is from Tunisia. The brother says in his message: I divorced my wife and did not inform her of it. I then met with her after divorcing her, and then I sent her to her parents' house. After that, she traveled to where I work. I then took her back by phone, but I have not yet written the formal taking back. She is currently at my house. Is it permissible for me to have intercourse with her when I return, before I write the formal taking back? Please advise us; may Allah reward you.
Answer: As long as the divorce was a single pronouncement and there were not two pronouncements before it, you may take her back, and having intercourse with her constitutes a taking back. However, it is better for you to have the intention of taking her back when you have intercourse.
The point is that the taking back is sufficient, and praise be to Allah, she is your wife now. If you had witnessed the taking back, that would have been better and more proper. If a person intends to take his wife back during intercourse, that is sufficient, and praise be to Allah. She is your wife, one pronouncement has passed, and he has two pronouncements remaining. However, if two pronouncements have already passed, this would be the third, and it is not valid. Yes.
The presenter: May Allah reward you.
