"A roasted mastigure was brought to the Prophet (ﷺ) who stretched his hand towards it to eat it. But it was
said to him, "It is a mastigure." So he withdrew his hand. Khalid asked, "Is it unlawful to eat?" the
Prophet said, "No, but it is not found in the land of my people and that is why I do not like eating it."
So Khalid started eating (it) while Allah's Messenger (ﷺ) was looking at him. An-Nadr said: 'Al-Khazira' (is
prepared) from bran while 'Al-Harira' is prepared from milk.
