Hazrat Sha’bi (may Allah have mercy on him) and Hazrat Hakam (may Allah have mercy on him) say that if a Muslim becomes an apostate and goes to the land of the disbelievers, then his wife, if she menstruates, will observe an ‘iddah of three menstrual cycles, and if she does not menstruate, then three months. If she is pregnant, her ‘iddah is until childbirth. After that, she may marry if she wishes. If her husband returns and repents before the completion of the ‘iddah, their marriage will remain intact.
