What is the expiation incumbent

Q 2: A person broke his Sawm (Fast) one day last year, thinking that is was lawful to break Sawm for study reasons. Later on, he made up for (Part No. 10; Page No. 356) this day. One day this year, he broke his Sawm deliberately.

A: It suffices him, besides turning to Allah in repentance, to make up for the day of Ramadan he missed thinking that it was lawful to break Sawm for study purposes. He should also make up for the other day.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
