Musannaf Ibn Abi Shaybah

Hazrat Ibn Abbas (may Allah be pleased with both of them) said regarding a child who kills a pigeon from among the pigeons of the Haram: He said (to the child's father), "Slaughter a goat on behalf of your child."

Hazrat Umar says that when we were young, we came with Hazrat Hafs bin Asim and caught a young pigeon in our house and started playing with it until it died. Hazrat Aisha (may Allah be pleased with her), daughter of Muti’ bin Al-Aswad, said to them, and they said that a goat should be slaughtered. So a goat was slaughtered and given in charity.

It is narrated from Hazrat Hisham bin Urwah that some children of Hazrat Urwah were playing with the chicks of the pigeons of Makkah Mukarramah. My respected father ordered a goat to be slaughtered, so it was slaughtered and then its meat was given in charity.

Hasan says that if a child kills any game or the like, then its expiation is upon the one who is performing Hajj with him.
