Musannaf Ibn Abi Shayba 28:618

Waki’ narrated to us, he said: Hisham al-Dastawa’i narrated to us, from Sa’id al-Thawwar, from Habban ibn ‘Uthman, from Umm al-Darda’, that she saw a person who took an ant or a flea and threw it into the fire. She said: "It is not appropriate for anyone to punish with the punishment of Allah."
