Musnad Ahmad 25:1100

Hashim narrated to us, Shu'bah narrated to us, he said: Ja'far ibn Iyas informed me, he said: I heard 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 from the ghee and the dried yogurt, but he left the dabb lizards out of disgust. He said: And it was 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).
