Does it necessitate ten expiations or a single expiation if an oath is repeatedly broken in different situations, taking into account the student's financial circumstances?

A Muslim should avoid excessive swearing. If he swears to do something, and then it becomes clear to him that something else is better, he should do that which is better and expiate for his oath. Expiation is required for every oath broken, if the oaths are multiple and concern different matters. The expiation for an oath is feeding ten poor persons, or clothing them, or freeing a slave. If one is unable to do that, then it is fasting for three days. Whoever does not possess money for expiation is not permitted to take from the wealth of his family or others without their consent; rather, he should move to fasting for three days.
