Should the Kaffarah for the missed day of Sawm be feeding a Miskin for an entire day or just one meal?

Q 3: How should I feed? Should I feed a Miskin (a needy person) for an entire day, that is, from the morning to the evening, or just one meal?

A: It suffices to give every one of the sixty Miskins 1/2 Sa` (1 Sa`=3 kg. Approx.) of the staple food eaten by your family. (Part No. 9; Page No. 219) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
