"Narrated Abdullah ibn Mas'ud: We were with the Messenger of Allah (peace be upon him) 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 Messenger of Allah (peace be upon him) 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."
