RasulAllāh صلى الله عليه وسلم said:
“There are no days wherein righteous actions are more beloved to Allaah than these ten days (of Dhul Hijjah).” They said: Not even jihad in the way of Allaah?
He صلى الله عليه وسلم said: “Not even jihad in the way of Allaah, except for a man who leaves out (for jihad) with his wealth and self and doesn’t return back with any of them.”
- Saheeh Bukhaari, Book of The Two Eids, Hadith #919
RasulAllāh صلى الله عليه وسلم was asked about fasting on The Day of ‘Arafah. [He, صلى الله عليه وسلم replied]: ‘Fasting on the day of ‘Arafah is an expiation of last year’s and next year’s sins.’
- Sunan Nisaa’i, 4/205 and Sunan Abu Dawud; classified by al-Albaani as saheeh in Saheeh Abi Dawud, 2/462
The Day of Arafah is the day before the day of Eid.
Fasting expiates minor sins of last and next years; for major sins, repentance is required.
It is not established in the Sunnah for pilgrims to fast this day. (source).
