Tying the donkey testes and the donkey dying

Q 1: We had a donkey that we used for carrying water from the well to the house. However, the donkey was very robust and we could not control it when it followed female donkeys because of our young age. Therefore, we and our grandmother tied its testicles so that it would not chase female donkeys for copulation, but this caused its death. We did not want to kill it, we just wanted to suppress its desire. Is there a Kaffarah (expiation) for this, Sheikh? May Allah reward you!

A: There is no compensation on you or your grandmother for causing the death of the donkey, since you did not intend to kill or harm it. (Part No. 26; Page No. 172) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
