Witnessing One's Wife Committing Adultery

Question: Should a man keep his wife or divorce her after he had witnessed her committing adultery? Will he be sinful if he does not divorce her?

Answer: If the husband loves her, is confident that she will not repeat herself and that there will be no breaches in either of their rights if he remains married to her, he may keep her as his wife. It is not at all necessary or Waajib (compulsory) to divorce her.

When a similar situation arose in the times of Rasulullaah SAW. he advised the man that he was at liberty to divorce his wife. However, when the husband submitted that he still loved her, Rasulullaah SAW. told him that he was welcome to remain married to her. And Allaah knows best what is most correct.
