I saw the Messenger of Allah (ﷺ) sitting neat the Black stone (or at a corner of the Ka'bah). He said: He (the Prophet) raised his eyes towards the heaven, and laughed, and he said: May Allah curse the Jews! He said this three times. Allah declared unlawful for them the fats (of the animals which died a natural death); they sold them and they enjoyed the price they received for them. When Allah declared eating of thing forbidden for the people, He declares it price also forbidden for them. The version of Khalid b. 'Abd Allah al-Tahhan does not have the words "I saw". It has: "May Allah destroy the Jews!"
