It was narrated from Abu Qataadah (may Allaah be pleased with him) that the Messenger of Allaah (peace and blessings of Allaah be upon him) was asked about fasting on the day of Arafah and he said: It expiates for the past and coming years. Narrated by Muslim (1162). According to another report: I ask Allaah that it may expiate for (the sins of) the year that comes before it and the year that comes after it.
