I was raised in my father's care, and when I grew up and reached manhood, my father married me off in exchange, and I did not know that exchange marriage is forbidden, but I heard that exchange marriage

The questioner : This is a message received from a listener of the program. He says in this question: "O honorable Shaykh, I have some questions, among which is this one. I mention that I was raised as a child in my father's care, and when I grew up, I say, and reached manhood, my father married me off in exchange, and I did not know that exchange marriage is forbidden. I have heard from some people that they say that exchange marriage with a daughter or a sister is forbidden. And we have heard that if the parties have agreed, then exchange marriage is not forbidden. Is this correct?"

The Shaykh : I say, if the matter is as stated in the question, that exchange marriage means he married me to your daughter and I will marry you to my daughter, or he married me to your sister and I will marry you to my sister, then it is obligatory for the two parties to return to the Sharia court, and whatever it rules is what is relied upon. Yes.

The questioner : May Allah reward you.
