What should I do about the accumulated oaths whose number I do not know, and how can I atone for them? And should I fast six days for the two oaths I did not fulfill this year?

One should not frequently swear by Allah, as it diminishes the reverence for Allah. There is no expiation for oaths broken before puberty, based on the hadith (definition): "The pen has been lifted from three: ... and from the child until he reaches puberty." As for what occurs after puberty, expiation is obligatory for each oath, by feeding ten poor persons, clothing them, or freeing a slave. If none of these is possible, then by fasting three days for each oath. If one cannot determine the number, then expiation is required for what he believes will clear his conscience.
