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.
‘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.”
Mujashi', who belonged to the B. Sulaim, said that God’s Messenger used to say, "A lamb may be given as full payment for that for which a kid is full payment.”
