Hadith.3442 - Al-Ala' narrated from Muhammad ibn Muslim, from one of the Imams, peace be upon them, who said
I asked him about a man who owned a bondwoman and said: "Whenever I approach her, she will be free." Then he sold her to another man and later bought her back.
Imam (as) said: "There is no harm in approaching her, as she had exited his ownership."
