Making the condition that one can break one's oath if one is unwell
Q: I made an oath to fast for a month but stipulated in the oath that if I felt unwell, I could break it. So, about a week in I had some discomfort in my chest, and felt that I should stop, so I did. (I did not break a fast). Does this mean there's no expiation? Because I gave myself some leeway in the oath I made.
Also, is it permitted to pay a charity to fulfill the kafaarat yameen on your behalf? If you make the expiation you are forgiven for breaking the oath by Allah azza wa jal?
