What is the ruling regarding a couple returning to each other after a single divorce, and is it permissible for the husband to live in the same house during the 'iddah period without seeing his wife, and what is the ruling regarding the wife's refusal to go to her father's house?

If a man divorces his wife with a revocable divorce, she has the right to remain in the marital home, and it is not permissible to expel her, due to the Almighty's saying: (Do not expel them from their homes, nor should they leave, unless they commit a clear immorality). During the 'iddah (waiting period), the husband can take his wife back through word or deed (such as sexual intercourse) without a new contract, because she is still considered his wife. If the 'iddah ends, she becomes irrevocably divorced with a minor irrevocable divorce, and she is not lawful for him again except with a new contract, mahr (dowry), and wali (guardian), and with her consent. Reconciliation is advised to preserve the family.
