From Sahih Muslim (Hadith 5031):
A hadith pertaining to the eating of the lizard is transmitted from the Prophet (ﷺ) on the authority of Ibn 'Umar, but in this very hadith narrated through a different chain of transmitters there is a slight variation of wording (and the words are):" A lizard was brought to Allah's Messenger (ﷺ) but he neither ate that nor declared it unlawful." And in the hadith transmitted through Usama (the words are):" The man (inquirer) was standing in the mosque and Allah's Messenger (ﷺ) was sitting on the pulpit
