Musnad Ahmad 25:1387

Yahya narrated to us, from Shu'bah, Abu Bishr narrated to us, from Sa'id ibn Jubayr, from Ibn Abbas, who said: Umm Hufayd, the maternal aunt of Ibn Abbas, gifted the Messenger of Allah (may Allah bless him and grant him peace) some ghee, dried yogurt (aqt), and dabb lizards. He ate the ghee and the dried yogurt, and he left the dabb lizards out of disgust. They were eaten at the table of the Messenger of Allah (may Allah bless him and grant him peace), and had it been forbidden, it would not have been eaten at the table of the Messenger of Allah (may Allah bless him and grant him peace).
