Never heard of that book or that person... so maybe you should do a little more checking. The Muslims I talked to about it just say. We don't talk about that...
They were taken out of the Koran and another revelation was added about when Satan throws in a lie, Allah will surely take it out, as with every other time Muhammad broke his own law and got a "revelation" to justify him. If you want I can get the exact scripture that talks about Satan putting the lie in. And the book and direct follower of your propehts name who attests to this.
