Commitments And Promises Made By Mistake
Take the example of an oath. Taking an oath is more serious a matter than a simple promise. Still, it is permissible to break the oath but atone for it by feeding 10 poor or keeping three consecutive fasting. So, if one feels some genuine need to break one’s promise, one can do it, but one should tell others who might be affected beforehand. The promises made with God in ignorance can be revoked. God is Merciful. He did not demand you those ones.
