A man invited us, and he brought out a tray bearing thirteen lizards. This was at supper. Some of us ate, and others refrained. The next morning we went to Ibn Abbas and asked him about it. Those sitting with him spoke at length on the matter, until one of them said, "The Messenger of Allah ﷺ said, 'I will neither eat it nor declare it forbidden.'"Ibn Abbas replied, "What a poor thing you have said. The Messenger of Allah ﷺ was sent only to declare what is lawful and what is forbidden."Then he said, "The Messenger of Allah ﷺ was at Maymunah's house, and with him were Fadl bin Abbas, Khalid bin Walid, and a woman. A tray was brought bearing bread and lizard meat. When the Messenger of Allah ﷺ reached out to take some, Maymunah said to him, 'Messenger of Allah, that is lizard meat.' He withdrew his hand and said, 'It is meat I have never eaten, but the rest of you may eat it.' So Fadl bin Abbas, Khalid bin Walid, and the woman ate. Maymunah said, 'I will not eat any food that the Messenger of Allah ﷺ has not eaten.'"
حدثنا يونس حدثنا عبد الواحد حدثنا سليمان الشيباني قال حدثنا
دعانا رجل فأتى بخوان عليه ثلاثة عشر ضبا قال وذاك عشاء فآكل وتارك فلما أصبحنا غدونا على ابن عباس فسألته فأكثر في ذلك جلساؤه حتى قال بعضهم قال رسول الله ﷺ لا آكله ولا أحرمه قال فقال ابن عباس بئسما قلتم إنما بعث رسول الله ﷺ محلا ومحرما ثم قال كان رسول الله ﷺ عند ميمونة وعنده الفضل بن عباس وخالد بن الوليد وامرأة فأتي بخوان عليه خبز ولحم ضب قال فلما ذهب رسول الله ﷺ يتناول قالت له ميمونة إنه يا رسول الله لحم ضب فكف يده وقال إنه لحم لم آكله ولكن كلوا قال فأكل الفضل بن عباس وخالد بن الوليد والمرأة قال وقالت ميمونة لا آكل من طعام لم يأكل منه رسول الله ﷺ
Its isnad is sahih. Sulayman Shaybani is Abu Ishaq, Sulayman bin Abu Sulayman. See 1978, 2299, 2354, 2569.As for his statement ﷺ, "I do not eat it, nor do I declare it forbidden," it is established as sahih, found in the two Sahihs and others, from the hadith of Ibn Umar. Ibn Abbas only objected to what the one narrating this in his gathering thought, namely that this was an indication of prohibition or dislike. So he objected to the narrator's understanding, not to what was narrated. See Muntaqa 4582, 4583.
