Abu al-Zubayr (may Allah have mercy on him) says: I asked Sayyiduna Jabir (may Allah be pleased with him) about the lizard (dabb), and he said: "Do not eat it," and he disliked it. The narrator says that Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) said: "The Messenger of Allah (peace and blessings be upon him) did not declare it unlawful, for Allah Almighty benefits some people by it, since this is indeed the food of the common people; had I had some, I would have eaten it."
