In Madina there is a guy who saw the prophet Mohammed, peace be upon him, say, "Tell my people that the Holy Koran says that you must says your prayers [5x daily] and send this message of mine everywhere." This guy who received this message also spread it to 7 people. So after precisely 10 days good will come to this house. Or, if you don't distribute it, then after 10 days grief will come.
===========================
I would say you would be quite safe to disregard that message, but I just wanted to write it out here for interest.
Well, whose isn't? :D
