Sahih Ibn Khuzaymah 2099 — the hadith of Sayyiduna Abu Qatadah

Imam Abu Bakr (may Allah have mercy on him) says that the hadith of Sayyiduna Abu Qatadah (may Allah be pleased with him) from the Noble Prophet (peace and blessings be upon him) that the fast of the day of Arafah becomes an expiation for the sins of the previous year and the coming year, I have already written in the chapter of Ashura.
