It is narrated from Hazrat Uqbah (may Allah be pleased with him) that I heard the Prophet (peace and blessings be upon him) say: "I fear for my Ummah regarding the Book and milk." Someone asked, "O Messenger of Allah (peace and blessings be upon him), what is meant by the Book and the other danger?" He replied, "The hypocrites will learn it and will argue with the believers, and they will love milk and because of it they will leave the congregation and will abandon the Friday prayers."
