Just because Quirrell says that he recently stole it does not mean it is true. Telling harry that it is stolen property is a good way to make sure he keeps it secret without causing any suspicion about the nature of the book. I think that the diary is a horcrux and another attempt to turn Harry over to his dark side permanently.
