Sunan Ibn Majah 3341

It was narrated that Ibn ‘Umar said:“One day, the Messenger of Allah (ﷺ) said: ‘I wish that we had some white bread made of brown wheat, softened with ghee, that we could eat.’ A man from among the Ansar heard that, so he took some (of that food) and brought it to him. The Messenger of Allah (ﷺ) said: ‘Where was this ghee kept?’ He said: ‘In a container made of mastigure skin.’ And he refused to eat it.”
