What is the ruling on a woman whose husband has passed away leaving her home to visit family and friends without spending the night outside the home, and what is the ruling on her residing in another marital apartment in a different city?

A woman whose husband has passed away observes her iddah (waiting period) in her home for four months and ten days. She should not leave at night except out of necessity. She is permitted to leave during the day for a need, such as visiting relatives or friends, though it is more cautious not to leave if there is no need. She observes her iddah in the marital home where she was residing at the time of his death, and it is not permissible for her to move from it, according to most scholars. If the husband had more than one home, she observes her iddah in the home where she received the news of his death.
