The ruling on a woman in the waiting period after her husband's death leaving her home for a need

Question:
May Allah reward you. Honorable Shaykh, this questioner says: My sister's husband passed away, and she is a teacher. They have exams these days. What is prescribed for her, Honorable Shaykh?

Answer:
It is obligatory for her to remain in the house, because this is one of the rulings of the waiting period after death. One of the rulings of the waiting period after death is the state of mourning (i'dad). If she needs to go out for the exam and she would miss the exam if she did not, she goes out during the day, takes the exam, and returns to her house when the exam is over. The daily exam is over. She goes out only as much as is needed and returns to her house, and this is during the day, not at night. Yes.
