Fātimah bint Qays (may Allah be pleased with her) told the Prophet (may Allah's peace and blessings be upon him) she feared that if she observed her waiting period in the house where she used to live with her husband before he divorced her, a licentious person or a robber might break into the house. So the Prophet (may Allah's peace and blessings be upon him) told her to move house, even though she was still in her waiting period following the divorce, as there was a need for it.
