If the waiting period of a wife in the state of revocable divorce has ended, does she return to her husband with a new contract, or is it sufficient to have witnesses?

The questioner : May Allah reward you, O honorable Shaykh. A man divorced his wife for the first time with a revocable divorce and did not take her back until the period for taking her back ended. He says: Does she return to me now with a new contract, or is it sufficient to have witnesses? Knowing that if it were with a new contract, they might take advantage of me and the taking back would become difficult?

The Shaykh : If the waiting period has completed, she becomes forbidden to the husband, and the husband becomes like any other man who proposes to her anew and contracts with her anew, and he must pay the mahr that the two parties agree upon. Allah the Exalted said: There is nothing [else], yes.
