Musnad Ahmad 27:609

He said: I found in my father’s book: Yazid ibn Harun narrated to us, Shu’bah informed us, from ‘Abdullah ibn Dinar, who said: I heard Ibn ‘Umar say: I heard the Messenger of Allah, peace and blessings of Allah be upon him, when a man asked him about the dabb (spiny-tailed lizard), he said: "I do not eat it, nor do I forbid it."
