It is a lizard. The Messenger of Allah (ﷺ) raised his hand. I (Khalid) asked: Is it forbidden, Messenger of Allah? He replied, No, but it is not found in the land of my people, so I find it distasteful. Khalid said: I then pulled it and ate it while The Messenger of Allah (ﷺ) was seeing.
Sunan Abi Dawud Book 28, Hadith 59
← Previous Hadith Ibn ‘Abbas said that his maternal aunt presented to the Messenger of Allah (ﷺ) clarified butter, lizards and cottage cheese. He ate from clarified butter and cheese, but left the lizard abominably. It was eaten on the food cloth of the Messenger of Allah (ﷺ). Had it been unlawful, it would not have been eaten on the food cloth of the Messenger of Allah (ﷺ).

Sunan Abi Dawud Book 28, Hadith 58 Next Hadith → We were in an army with the Messenger of Allah (ﷺ). We got some lizards. I roasted one lizard and brought it to the Messenger of Allah (ﷺ) and placed it before him. He took a stick and counted its fingers. He then said: A group from the children of Isra'il was transformed into an animal of the land, and I do not know which animal it was. He did not eat it nor did he forbid (its eating).
