Sahih Muslim Book 21, Hadith Number 4792.

Chapter : Pertaining to the flesh of the Lizard.

Khalid b. Walid reported that he visited Maimuna daughter of al-Harith with the Messenger of Allah (may peace be upon him), and she was the sister of his mother. She presented to Allah’s Messenger (may peace be upon him) the flesh of a lizard which Umm Hufaid daughter of al-Harith had brought from Najd, and she had been married to a person belonging to Banu Ja’far. It was the habit of Allah’s Messenger (may peace be upon him) not to eat anything until he knew what that was. The rest of the hadith is the same but with this (addition): “Ibn al-Asamm narrated it from Maimuna and he was under her care.”
