Maliks Muwatta Book 54, Hadith Number 11.
Section : Eating Lizards.
Malik related to me from Abdullah ibn Dinar from Abdullah ibn Umar that a man called the Messenger of Allah and said, “Messenger of Allah, what do you think about lizards?” The Messenger of Allah, may Allah bless him and grant him peace, said, “I do not eat them, and I do not forbid them.”
