It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) was sitting behind Maqam Ibrahim (peace be upon him), then he raised his blessed head towards the sky, looked for a long time, then smiled and said: "May Allah destroy the Jews; fat was made unlawful for them, so they sold it and began to consume its price. Indeed, when Allah the Exalted makes something unlawful for a people to eat, He also makes its price unlawful for them."
