Is it allowed to sacrifice an animal that was purchased for Eid al-Adha but has now been hurt in a part of its body (e.g., leg) and the injury cannot be healed before the day of sacrifice?
If it is a mustahab sacrifice for the day of Adha, then there is no problem if it has an injury, but it has to be slaughtered on the tenth of Dhul Hijjah up until the 12th.
