Sahih Bukhari, Chapter: Sales and Trade

Allah's Apostle said, "By Him in Whose Hands my soul is, son of Mary Isa (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 nobody will accept charitable gifts.
