Will my wife be divorced if I swore an oath of divorce upon her in a state of anger when I suspected her, and then I suspected her again?

It was not clarified what the oath was taken upon. If the oath was by Allah or by divorce, and the doubt upon which the divorce was suspended occurred, then, according to the majority of jurists, the divorce takes effect. However, Sheikh al-Islam Ibn Taymiyyah holds that a suspended divorce does not take effect unless it was intended. As for anger, it prevents the occurrence of divorce in some circumstances. One must think well of a Muslim and not swear an oath except by Allah Almighty. Swearing by divorce is blameworthy and should not be used as a means to resolve marital problems.
