Is it permissible for a woman to leave and observe her waiting period in the house of one of her daughters?

Question:
May Allah forgive you. This questioner says: There is a woman whose husband has passed away, and she is currently in the prescribed waiting period, but she is now alone in the house and has no children. Her husband has passed away, and she is now in the prescribed waiting period, but she is alone in the house, in her own house, and she feels lonely and alone, and she may feel afraid. So, is it permissible for her to move to one of her daughters in another city, given that she has not left the house, but will remain in it?

Answer:
It is obligatory for the widow to observe her waiting period in the house; because the Messenger (peace and blessings be upon him) said to the woman who had pronounced zihar: "Stay in your house until the time is fulfilled." If she is able to do so, that is the case. However, if she is in danger or fear, and there is no one with her to keep her company, there is no harm in her moving. But if she is able to remain, she must remain in the house.
