Musnad Ahmad 25:1304

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Abu Bishr, from Sa'id ibn Jubayr, who said: I heard Ibn Abbas saying: My maternal aunt, Umm Hufayd, gifted the Messenger of Allah (may Allah bless him and grant him peace) some ghee, dried yogurt (aqt), and dabb lizards. He ate from 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).
