Does a divorce pronounced by the husband with the words "He divorced me before God" take effect?

You erred by leaving your husband's house without his permission, so repentance is incumbent upon you. Try to contact your husband and apologize to him, and if the attempt is not fruitful, seek the mediation of trustworthy individuals between you. If no one helps you, then go to your husband's house yourself with your clothes; for it is still your home if it was the first or second divorce and the waiting period (iddah) has not expired. Repeat attempts at reconciliation and do not despair, for the righteous wife is "the loving, the fertile, who, when she wrongs or is wronged, says: I shall not taste slumber until you are pleased."
