Musnad Ahmad 2661
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Barakah bin al-’Uryan al-Mujashi’i said : I heard Ibn Abbas (رضي الله عنه) say: The Messenger of Allah (ﷺ) said: "May Allah curse the Jews; animal fat was forbidden to them, so they sold it and consumed its price. When Allah, may He be glorified and exalted, forbids eating something, He also forbids its price."
