What is the legal ruling for a man who falsely swore to his wife by divorce, "You are divorced if I spoke to any woman" and "You are divorced if I did not become acquainted with any woman," when he does not desire divorce, and why did the fatwas differ between the occurrence of divorce and the obligation of two expiations for the oath?

You erred by engaging in a forbidden relationship. As for conditioning divorce twice on a past event that you know occurred, while you are untruthful in your statement, this falls under the ruling of a "ghamus" (perjurious) divorce oath. Two divorces are binding upon you according to the majority of scholars. You may take your wife back if her iddah (waiting period) has not expired and you had not divorced her previously. If her iddah has expired and there was no prior divorce, then renewing the marriage contract is necessary. If she had a previous divorce, then she is forbidden to you until she marries another husband and he divorces her after consummation. The opinion that only two expiations for an oath are binding is the view of some scholars.
