Question: If one makes a nazr(do something if something happens) and is unable to fulfill it. What is the kaffarah?
Answer: The kaffarah of oaths is freeing a slave or feeding ten poor 2 complete daily meals or clothing them. If unable to do any of these, one may fast 3 days.

For example if the nathr was made to fast a specific day, and one missed it, then one must fast another day instead.
