‘A’isha reported God’s Messenger as saying, "On the day of sacrifice no one does a deed more pleasing to God than the shedding of blood. The sacrifice will come on the day of resurrection with its horns, its hairs and its hoofs, and the blood finds acceptance with God before it falls on the ground, so be glad about it.”
Ibn ‘Abbas said, "We were with God’s Messenger on a journey when the day of sacrifice came, and we shared with one another, seven for a cow and ten for a camel.”
Tirmidhi, Nasa’i and Ibn Majah transmitted it, and Tirmidhi said this is a hasan gharib tradition.
Abu Huraira reported God's Messenger as saying, "There are no days on which God likes better to be worshipped than the ten days of Dhul Hijja. Fasting observed on each of these days is equivalent to a year’s fasting, and prayer during each of these nights is equivalent to prayer during Lailat al-qadr.’*
* A night towards the end of Ramadan. See Book 7, Chap. 9.
Tirmidhi and Ibn Majah transmitted it, but Tirmidhi said its isnad is weak.
