The nature of shighar marriage and its ruling

From Buraydah in the Qasim region, listener Muhammad ......... sent a message containing three questions. In the first question, he asks: What is shighar marriage? Please inform us, may Allah reward you with good?
Answer: Shighar marriage is when each of the two guardians conditions the marriage of the other’s female relative. One of them says, “I will marry you to my daughter on the condition that you marry me to your daughter,” or “my sister on the condition that you marry me to your sister,” and so on for anything similar to that. That is, each one conditions the marriage of the other. Zayd proposes to Hind, and 'Amr proposes to Zayd’s sister. Each one conditions the other: Zayd conditions 'Amr, and 'Amr conditions Zayd regarding his sister, or his daughter, or his brother’s daughter. This is shighar; based on the saying of the Prophet (peace and blessings be upon him): . This is shighar, meaning the mutual conditioning in marrying a woman to a person, whether she is his daughter, his sister, his brother’s daughter, or his paternal cousin’s daughter. He says, “I will marry you to her, but on the condition that you marry me to your daughter, or your sister, or something similar to that.” This is not permissible, and the mahr (bridal gift) in this case is invalid. However, if he proposes to you and the other proposes to you without any mutual conditioning, there is no harm. He proposes to this man’s daughter, and this man proposes to the other’s daughter, and the other proposes to his daughter or his sister, without any mutual conditioning. Yes.
