Doing iddat in one's own home
Q: A poor woman who works as a full-time caretaker of another woman had the death of her husband. In this situation, is it permissible to do iddat in the house where she works since she is the only one to support her children and if she goes to her own home for iddat, she will not have any source of income?
Some people are willing to help her financially for the period of iddat to do iddat at her own home. What will be the best in these circumstances?
