Are the sacrificial animals and all that is slaughtered as an offering to God from the animals of Paradise?

There is no evidence that sacrificial animals (adhaahi) become animals of Paradise. While a very weak hadith from Zayd ibn Arqam suggests that a Muslim is rewarded for their sacrifice according to the number of hairs on the animal, this is not a strong proof. It has been reported that sheep are among the animals of Paradise, but sacrificial animals are not limited to sheep.
