Abu Dawud Book 8, Hadith Number 2669.

Narated By Abdullah ibn Mas’ud : We were with the Apostle of Allah (PBUH) during a journey. He went to ease himself. We saw a bird with her two young ones and we captured her young ones. The bird came and began to spread its wings. The Apostle of Allah (PBUH) came and said: Who grieved this for its young ones? Return its young ones to it. He also saw an ant village that we had burnt. He asked: Who has burnt this? We replied: We. He said: It is not proper to punish with fire except the Lord of fire.
