Musnad Ahmad 2214

It was narrated from Barakah Abul-Waleed: Ibn 'Abbas (رضي الله عنه) told me: The Messenger of Allah was sitting in the mosque, facing the [Black] Stone, then he looked at the sky and smiled, then he said: "May Allah curse the Jews; animal fat was forbidden to them, so they sold it and consumed its price, But when Allah forbids people to eat something. He also forbids its price to them.”
