The ruling on combining the intention of making up a fast with the Day of 'Arafah

Question:
The Shaykh: A man has a day of Ramadan to make up, and he wants to fast the Day of 'Arafah in its place.

Answer:
No, that is not permissible. The day of Ramadan is obligatory for him, and the Day of 'Arafah is a recommended practice. He should fast the day he owes, and when the Day of 'Arafah comes, he should fast it seeking the virtue, the virtue of the Day of 'Arafah. He does not combine the two. He fasts the make-up fast he owes, and when the Day of 'Arafah comes, that is an addition of good; he fasts it as a voluntary act. Yes.
