A:The Iddat of a widow is one hundred and thirty days. It is not permissible for her to leave the Iddat home for the purpose you mentioned. Iddat is a command from Allah Ta’aala and His Rasool (Sallallaahu Alayhi wa Sallam). Breaking a command of Shari’ah is a major sin. If she goes, she will be committing a major sin. She must remain and complete her Iddat. She may travel anywhere after the Iddat is over.
