What is the validity of a contract that a father was forced into to save his daughter from the young man who bewitched her, and is the contract considered void, and what should the father do if the young man refuses to terminate the contract?

If the guardian contracts his daughter's marriage due to fear of harm from the suitor that cannot be prevented, then this is compulsion that invalidates the contract. However, if he can prevent the harm, and the contract was made under social pressure, it appears that the contract is valid. The validity of the contract is not precluded by the witnesses not seeing the wife, as the witnessing is for the offer and acceptance. Scholars differed regarding the condition of witnesses knowing the wife; some hold that it is not a condition, while others deem it a condition that they know her name and lineage or see her. If the wife is unwilling, she can request a divorce or khul'.
