There are many people who have written such books in the past and there are many scholars who refuted them and I am sure someone refuted this book too, but some people are out there who enjoy spending their lives trying to dishonour others specially they like to point fingers at people at the highest status, inshaAllah in the end they will be dishonoured. I don't see why we need to waste our time with this thread, moderators please delete it. Wassalamu Alaikum.
