The Prophet ﷺ was asked about the lizard, and he replied, "I do not eat it, but I do not forbid it either."
سئل النبي ﷺ عن الضب؟ فقال: لست بأكله ولا بمحرمه.
Malik narrated it in Chapter on Seeking Permission (11) from Abdullah bin Dinar, from Abdullah bin Umar, and mentioned it. Bukhari narrated it in Chapter on Slaughtered Animals and Hunting (5536), and Muslim in Chapter on Hunting and Slaughtered Animals (1943:39), both through other routes from Abdullah bin Dinar, and mentioned it.As for what is reported from Ibn Umar, that he was asked about the lizard, and said, "Ever since the Messenger of Allah ﷺ said what he said about it, we have stopped eating it," I have not been able to locate this.Tabarani narrated it in Al-Kabir, and I have not been able to locate its chain of transmission, but Haythami mentioned it in Al-Majmu (4/37) and said, "Tabarani narrated it in Al-Kabir, and its chain is hasan." A portion of Musnad Ibn Umar has recently been published, and this hadith is not in it.
