Hazrat Sha'bi (may Allah have mercy on him) narrates that a man came before Shurayh and said that he had given his wife three divorces during her menstrual period. Shurayh said: Have you mixed the lawful with the unlawful and the pure with the impure? Now let her become pure, then let her menstruate again, then she will not be lawful for you until she marries another husband.
