Musnad Ahmad 1153:1092

Yazid narrated to us, Hammad ibn Salamah informed us, from Hammad, from Ibrahim, from al-Aswad, from Aisha, who said: A dabb (lizard) was brought to the Prophet, peace and blessings of Allah be upon him, and he did not eat it. I said, "Shall we not feed it to the poor?" He said, "Do not feed them from what you do not eat."
