The ruling on fasting on Friday if it coincides with the Day of 'Arafah

Question:
She says: The Day of 'Arafah fell on a Friday, and I fasted on that Friday, which was the Day of 'Arafah, but I did not fast on the Thursday. Do I have a sin upon me?

Answer:
We hope that there is no sin upon you; because you did not intend to fast it alone, but rather you fasted it only because it is the Day of 'Arafah. However, if you had fasted the Thursday with it, that would be more cautious; because the Messenger of Allah (peace and blessings be upon him) forbade fasting on Friday alone for the one who is performing a voluntary fast. So you are performing a voluntary fast, and if you fast the Thursday with it, it will be more cautious, even if your intention was for the sake of 'Arafah. But it is more cautious for the believer to seek to align with the Prophet (peace and blessings be upon him) and to comply with what he commanded.
As for fasting it alone with the intention of its virtue, this is not permissible; because the Messenger of Allah (peace and blessings be upon him) forbade that. But if he fasts it because it is the Day of 'Arafah, we hope that there is nothing upon him. But if he exercises caution and fasts the Thursday with it, it will be safer. Yes.

The presenter: May Allah reward you with good, and may He do you good.
