Once 'Umar was informed that a certain man sold alcohol. 'Umar said, "May Allah curse him! Doesn't he know that Allah's Apostle said, 'May Allah curse the Jews, for Allah had forbidden them to eat the fat of animals but they melted it and sold it."

Allah's Apostle said, "By Him in Whose Hands my soul is, son of Mary (Jesus) will shortly descend amongst you people (Muslims) as a just ruler and will break the Cross and kill the pig and abolish the Jizya (a tax taken from the non-Muslims, who are in the protection, of the Muslim government). Then there will be abundance of money and no-body will accept charitable gifts.
