ما هي كفارة من حلف بالخروج عن الإسلام واليهودية بسبب غضب شديد، ثم حنث بيمينه بعد أن ذهب إلى العمل؟

Swearing by a religion other than Islam is forbidden and necessitates repentance. Its perpetrator does not become an infidel unless he intended to be pleased with disbelief. The expiation for such an oath is a matter of scholarly disagreement, with the strongest opinion being that it is not obligatory. However, performing it is better to avoid the disagreement.
