Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated from Ibn ‘Abbas (رضي الله عنه) that The Prophet (ﷺ) said: "May Allah curse the Jews, animal fat was forbidden to them, so they sold it and consumed its price. But when Allah forbids something to people, He also forbids its price to them."
