What is khul'?

The Shaykh : In this case of khul', it is the woman who is the cause. Khul' and mukhala'ah are well-known Arabic terms. "Khul'" means to remove one's garment, so mukhala'ah of a woman means separating from her, but not through the method of divorce. A man's separation from his wife such that she becomes a stranger to him in the Shari'ah has two ways: the way of divorce, which is known to everyone, and the other way is mukhala'ah. I mentioned earlier that the cause of mukhala'ah is the woman, and it is not permissible for the man to be the cause. The wife, okay, this chair is empty.
The student : One of the brothers can come and sit on it.

The Shaykh : No, for some reason, it may be religious, it may be worldly. The wife does not find life with her husband pleasant, so she asks him for separation, and deep down he does not want to separate from her; he wants her to remain his wife for the rest of his life, and she is insistent on separation. Here is the answer to your question: he has the right to separate from her either through the way of divorce or through the way of mukhala'ah. We said divorce is known, but here mukhala'ah is that the woman ransoms herself.
