Question: Zaid and Maryam had an argument and Maryam was talking alot of nonsense, so Zaid told his wife,” If you do not stop talking, I will give you a talaaq.” Will this mean that Maryam is divorced?
Answer: No, this was a threat and a promise that he will divorce her. He did not issue a talaaq. The marriage is not broken.
