Abdullah bin Abbas reported,
The first time we heard of faludhaj was when Jibreel 
came to the Prophet ﷺ and said, "Your nation will have lands opened to them, and worldly riches will pour over them so abundantly that they will eat faludhaj."The Prophet ﷺ asked, "What is faludhaj?"Jibreel replied, "They will mix clarified butter and honey together."At this, the Prophet ﷺ gasped with a deep sigh.
Ibn Majah 3340
Daifحدثنا عبد الوهاب بن الضحاك السلمي أبو الحارث حدثنا إسمعيل بن عياش حدثنا محمد بن طلحة عن عثمان بن يحيى
عن ابن عباس قال
أول ما سمعنا بالفالوذج أن جبريل عليه السلام أتى النبي ﷺ فقال إن أمتك تفتح عليهم الأرض فيفاض عليهم من الدنيا حتى إنهم ليأكلون الفالوذج قال النبي ﷺ وما الفالوذج قال يخلطون السمن والعسل جميعا فشهق النبي ﷺ لذلك شهقة

[Its chain of transmission is very daif] Ibn Jawzi narrated it in al-Mawdu'at, 3/21, from the hadith of Ismail bin Ayyash, with this wording, and Yahya bin Ward followed him in narrating it. Ibn Jawzi said, "This hadith is false, with no basis." Uthman bin Yahya is unknown, I found no one who declared him trustworthy, and Azdi declared him daif.
