If a man marries a woman for the purpose of tahlil, and then he decides to keep her, is the contract valid?

The Shaykh : He says: If a man marries a woman with the intention of tahlil, and then he decides to keep her and does keep her, what is the ruling on the intention here? Is it valid or what? We ask for an elaboration with details.
In reality, it does not need elaboration or details. This contract is invalid, and it does not reach the first husband. It is obligatory for the second husband to separate from her. Then, if he desires to marry her after that with a valid contract, it is valid. Did you hear, Hajjaj? I say this: the marriage is not valid, and it does not need details or anything.
