Animals that have the following defects cannot be sacrificed:

1. An animal that was born without horns or the horns had broken off from the middle, can be used for Qurbani. If the horn has broken off from the root, it cannot be used for Qurbani.
2. Those animals that are totally blind or have lost one-third or more of their eye-sight, or one-third or more of the tail is cut, are not allowed for Qurbani.
3. An animal which limps and walks on three legs and cannot put the injured (4th) leg onto the ground, or that it can put the injured leg onto the ground, but is unable to walk on it, cannot be used for Qurbani. However, if it is unable to walk on it, but can still take support from it, then Qurbani is allowed with it, even though it is limping.
4. Animals having no teeth at all cannot be used for Qurbani. If an animal has lost some teeth only, and has most of the teeth, Qurbani is permissible with it. If most of the teeth are lost, Qurbani is not proper with that animal.
5. Animals born without ears cannot be used for Qurbani. Animals with very small ears can be used for Qurbani.
6. Animals that are so thin and weak or sick that they are unable to walk to the place for slaughtering, cannot be used for Qurbani.
7. If an animal sustains an injury whilst slaughtering, ea. a leg breaks or an ear is cut etc. the Qurbani of such an animal will be valid.
8. An animal was bought in a healthy and perfect state. After purchasing it, an accident occurred which rendered the animal unfit for Qurbani. In such a case, if the purchaser is not wealthy (Saahibe Nisaab), it will be permissible to offer the same animal for Qurbani. If the purchaser is Saahibe Nisaab, then it is compulsory upon him to obtain another animal in place of the injured animal.
9. If an animal bought for Qurbani gives birth (before being slaughtered), then this newly born animal should also be slaughtered.
