سنن النسائي

It was narrated from Ibn ' Abbas that: Khalid bin Al-Walid said that he entered upon Maimunah bint Al-Harith, who was his maternal aunt, with the Messenger of Allah, and some meat of a mastigure was offered to the Messenger of Allah (ﷺ) The Messenger of Allah (ﷺ) would not eat anything until he knew what it was. One of the women said: "Why don't you tell the Messenger of Allah (ﷺ) what he is eating?" So she told him that it was the meat of a mastigure, and he stopped eating. Khalid said: "I asked the Messenger of Allah (ﷺ) 'Is it Haram?' He said: "No but it is a food that is no9t known in the land of my people, and I find it distasteful."" Khalid said: " I pulled it over toward myself and ate it, and the Messenger of Allah (ﷺ) was watching me." And Ibn Al-Asamm narrated it from Maimunah, and he was in her apartment.
