Based on the mentioned facts, what is the number of rak'ahs and parts that must be performed to fulfill the vow, and should they be fulfilled in one day or over multiple days? How many expiations for an oath (kaffarat yamin) are due if that option is chosen, and does the first expiation nullify the vow? What should I do to free myself from this vow? What is the obligatory expiation for an oath upon me? What is "breaking an oath" (al-hanth)?

Whoever suffers from obsessive doubts and uncertainty regarding an oath or a vow should know that certainty is not dispelled by doubt, and legal rulings are not established by it. A vow is renewed by repeating the action if its wording indicates repetition (e.g., "whenever," "however much") or if this was intended. However, for one whose wording did not indicate repetition and who did not intend for the vow to be repeated, a single expiation suffices, even if the action is repeated. The expiation for a vow is the expiation for an oath (freeing a slave, or feeding ten poor people, or clothing them); if unable to do so, then fasting for three days. Breaking a vow necessitates the expiation for an oath, and one is not exempted from fulfilling it due to studies or examinations.
