Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) related that the Messenger of Allah (peace and blessings be upon him) said: "It is not lawful for a woman to give permission (to anyone to enter) in her husband's house without his permission, nor to go out while he dislikes it, nor to forsake his bed, even if he is more unjust to her, nor to shun him, even if he is unjust, until she comes to him and apologises to him. Then if he accepts her apology, (well and good); otherwise Allah accepts her apology."
