Does one who says "I am an infidel" disbelieve if he did a specific act, intending disbelief and not merely prohibition, and then regretted it and wished to do what he had sworn to do?

Whoever says, "I am a disbeliever" intending disbelief, immediately becomes a disbeliever. As for someone who says it to distance himself from a certain action, or utters it casually, he does not become a disbeliever. He should say, "There is no god but Allah, Muhammad is the Messenger of Allah" and seek Allah's forgiveness. However, if he intended to be pleased with disbelief if he were to do the sworn-upon act, he becomes a disbeliever immediately. But if he regrets and repents, his repentance is hoped to be accepted if its conditions are met. If he then performs the sworn-upon act, there is no sin upon him if the act is permissible, because this utterance does not constitute an oath, and disbelief does not occur as long as he regretted the intention of disbelief. If the act was forbidden, he sins by doing it but does not become a disbeliever.
