“The first we heard of Faludhaj* was when Jibril (as) came to the Prophet (ﷺ) and said: ‘The world will be opened for your nation and they will conquer the world, until they eat Faludhaj.’ The Prophet (ﷺ) said: ‘What is Faludhaj?’ He said: ‘They mix ghee and honey together.’ At that, the Prophet (ﷺ) sobbed.”
Sunan Ibn Majah Book 29, Hadith 90
