What is the ruling regarding a woman who has been irrevocably divorced three times (major, irreversible divorce) and leaves her home in the first week of her divorce, and does a divorced woman have an 'iddah (waiting period)?

A woman who has been divorced three times with an irrevocable major divorce (baynunah kubra) must observe an 'iddah of three menstrual cycles (quru'). It is not permissible for her to leave her home except out of necessity or need. If she leaves without a need, she must repent and return.
