THE FIRST TEN DAYS OF ZUL-HIJJAH
Rasulullah (Sallaahu ‘alayhi Wasallam) said: “On no days is the worship of Allah desired more than in the first ten days of Zul Hijjah. The fast of each of these days is equal to the fast of a whole year, and the Ibaadat (worship) of each of these nights is equal to the Ibaadat of Laylatul Qadr.”
[Tirmidhi / Ibn Majah]
Hadhrat Ibn `Abbas (Radhiyallahu 'Anhu) reported that Rasulullah (Sallaahu ‘alayhi Wasallam) said: "There are no days in which righteous deeds are more beloved to Allah than these ten days."
The people asked: "Not even Jihad for the sake of Allah?"
He (Sallaahu ‘alayhi Wasallam said: "Not even Jihad for the sake of Allah, except in the case of a man who went out, giving himself and his wealth up for the cause (of Allah), and came back with nothing."
Hadhrat Abdullah Ibn 'Umar (Radhiyallahu ‘Anhu) related that Rasulullah (Sallaahu ‘alayhi Wasallam) said: "No days are as weighty with Allah and so liked by Him for good deeds than the first ten days of Zul Hijjah. So on these days increasingly read:
SubhaanAllah, Laa ilaaha illallaah, Alhamdulillah and Allahu Akbar."
THE DAY OF ARAFAH (9th of ZUL HIJJAH)
Hadhrat Talhah (Radhiyallahu 'Anhu) reported that Rasulullah (Sallaahu ‘alayhi Wasallam) said:
"Apart from the day of the Battle of Badr there is no day on which the shaytaan is seen to be more humiliated, more rejected, more depressed and more infuriated, than on the day of Arafah, and indeed all this is only because of beholding the abundance of descending mercy (on the day) and Allah's forgiveness of the great sins of the servants."
Rasulullah (Sallaahu ‘alayhi Wasallam) was asked about fasting on the Day of Arafah (the 9th Zul Hijjah).
He (Sallaahu ‘alayhi Wasallam) said: "It atones for the sins of the previous year and of the coming year."
