Lady Aisha Siddiqa (may Allah be pleased with her) narrates: It was asked from the Prophet Muhammad (peace be upon him) about a person who gives his wife an irrevocable divorce, then that woman marries another man, and before the second man has intercourse with her, he divorces her. Can that woman return to her first husband? The Prophet Muhammad (peace be upon him) said: No, not until (the second husband) tastes her honey as the first husband tasted. (Imam Ibn Hibban, may Allah have mercy on him, says:) In the Book of Allah, this ruling is mentioned in general terms: "If the man divorces her, she is not lawful for him thereafter until she marries another husband." So Allah Almighty has permitted for the first husband that he may marry her when she marries another man, but the Sunnah has clarified that such a woman is not lawful for the first husband until there is intercourse between the woman and the second husband, which is the tasting of honey, and then after that, if she is separated from him due to divorce or the husband's death, then at that time she will be lawful for the first husband.
