Is it permissible to fast the three days as expiation for the varying oaths, or must they be fasted consecutively, and what is the monetary value of feeding the poor if paid in cash?

The ruling on retracting an oath depends on the ruling of the matter sworn upon. If it was to abandon something forbidden or perform an obligation, then breaking the oath is forbidden. If it was about something disliked (makruh) or recommended (mustahabb), then breaking the oath is disliked. If it was about something permissible (mubah), then breaking the oath is permissible. If it was to perform something disliked or abandon something recommended, then breaking the oath is recommended. If it was to perform something forbidden or abandon an obligation, then breaking the oath is obligatory. When breaking an oath, expiation (kaffarah) becomes obligatory, which is feeding ten poor people, or clothing them, or freeing a slave. If you are unable to do so, then fast for three days. It is not permissible to pay the equivalent value. There is a difference of opinion among scholars regarding the condition of continuous fasting, and the more cautious approach is continuity.
