Does fasting on the Day of 'Arafah expiate major sins?

Question : The last question, Shaykh, may Allah preserve you. Some people, Shaykh, also commit sins, and they may commit major sins, and they say, "I will fast on the Day of 'Arafah, and it expiates two years, past and future." So, Shaykh, does the Day of 'Arafah expiate all sins?

Answer : No, it only expiates minor sins according to the majority of scholars. As for major sins, repentance is obligatory for them. If the five daily prayers, from Friday to Friday, and from Ramadan to Ramadan do not expiate anything but minor sins, and they are pillars of Islam, how can the fasting of the Day of 'Arafah be otherwise? It only expiates minor sins. Then, even if we assume it covers hidden sins and major sins, is it certain for every person who fasts on the Day of 'Arafah that his sins have been expiated? There may be obstacles that prevent the expiation. May Allah reward you with good, my brother. Thank you, my brother, may Allah...
