Does a divorce that occurred against the husband's will and due to family and legal pressures take effect, knowing that he had intercourse with his wife during the waiting period?

If the matter is as mentioned, then the divorce does not take place because it was issued under duress, for the Prophet, peace and blessings be upon him, said: "There is no divorce and no manumission in a state of compulsion." This is the view of the majority of scholars, contrary to Abu Hanifa. Therefore, the wife is still under your marital bond. Even if we were to assume it occurred for the sake of argument, your sexual intercourse with her with the intention of reconciliation before her waiting period ends is considered a reconciliation.
