How and based on what did you decide to give kafarah? When a woman misses some of her fast due to her menses, she must fast them later.

 

As for the kidney stones: Consult a Muslim doctor to find out if she can fast or not. If her illness is not permanent, she must make up for all these days missed as soon as she is able to.

My mom has issue of kidney stones due to which she is unable to fast the complete Ramadan since 6 yrs. Also before that she didn’t make up for the fasts missed due to mensus. We decided to give kuffara for the fasts missed due to mensus. Should we give kuffara for the fasts missed due to the stone problem? Does my mom come under those exempted from fasting as doing so causes pain
