Musnad Ahmad 33:569

Hassan narrated to us, Ibn Lahi'ah narrated to us, Abu al-Zubayr narrated to us, he said: I asked Jabir about the dabb (spiny-tailed lizard), and he said: It was brought to the Messenger of Allah, may Allah bless him and grant him peace, and he said: "I do not eat it," and he considered it repulsive. Umar ibn al-Khattab said: "The Messenger of Allah, may Allah bless him and grant him peace, did not forbid it, and Allah, the Mighty and Majestic, brings benefit through it to more than one person, and it is the food of the common shepherds. If I had some, I would have eaten it."
