The animals that are sacrificed are sheep, Goats, Camels, Cows mostly. Prophet Muhammad Peace Be Upon him has taught to do sacrifice of a good and healthy animal. Here are some things that you must keep in mind while choosing a animal for Qurbani:
1 Animal must be at least 2 years old if its a cow and 1 year old if its a goat. In case of Camel it should be at least 5 years old. Sacrifice of younger animal is not right.
2 Animal must be healthy. all his parts like legs, eyes, teeth, horns should be fine.
3 Qurbani of ill animals is not right.
4 Qurbani of Castrated animal can be done.
5 Qurbani of Barren animal can be done.
6 Blind animals are not eligible for Qurbani,.
Prophet Muhammad Peace Be upon him always preferred healthy animal for the sacrifice. doing Qurbani is a great virtue. according to Hadith of Rasool Allah SAW There is nothing dearer to Allah during the days of Udhiya than the sacrificing of animals.
May Allah SWT accept our sacrifices on this Eid Al Adha Ameen.
