1- Abu Qatadah (may Allah be pleased with him) is reported to have said that the Prophet (peace be upon him) said:“Fasting on the day of Arafah is an expiation for two years, the year preceding it and the year following it.

3- `Uqbah ibn `Aamr (may Allah be pleased with him) is reported to have said that the Messenger of Allah (peace be upon him) said: “The day of Arafah [for those performing Hajj], the day of sacrifice, and the days of Tashreeq are `Eids (feasts) for us – the people of Islam – and they are days of eating and drinking.” (Ahmad, Abu Dawud, and An-Nasa’i)
4- Abu Hurairah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) forbade fasting on the day of Arafah for one who is actually at Arafah. (Ahmad, Abu Dawud, An-Nasa’i, and Ibn Majah)
