The Book of Games and the Animals which May be Slaughtered and the Aninals that Are to be Eaten (Kitab-us-Said wal-Dhabaih wa ma Yukalu min Al-Hayawan)
Book Number: 021 / Hadith Number: 4787
A hadith pertaining to the eating of the lizard is transmitted from the Holy Prophet (may peace be upon him) 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 (may peace be upon him) 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 (may peace be upon him) was sitting on the pulpit."
