Breaking Sawm before sunset

A: The time of Sawm begins at the break of the second dawn and lasts until sunset. If someone observing Sawm eats before sunset, their Sawm is invalidated and they should make up for it if the Sawm is Wajib (obligatory), but if the Sawm is Nafilah (supererogatory), there is no blame on them for what they did, and they do not have to make up for it.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
