Is it permissible for a sixty-year-old woman, whose husband died abroad and was buried in his homeland, to return to the place of his death after forty days to settle financial obligations that she was entrusted with, and what is the ruling of Islamic law regarding her iddah (waiting period)?

A woman observing her waiting period (iddah) must remain in the house where she received news of her husband's death, and it is not permissible for her to move from it except out of necessity. If the woman has moved from her husband's house after his death, she must return to it to complete her waiting period, while also adhering to the regulations of mourning.
