answer by imam hussain kairanvi,
what a co-incident, the author first wrote the history of muhammad the prophet before and after, from one century a.d. to 2000 century ,
robert spencen in history, showed the impact of muhammad, in 1400 years, and still robert spencer feel the impact,
then robert spencer wrote a book, on the life of muhammad " the truth about muhammad,
and now the same robert spencer writing a book, about muhammad that, muhammad exist or not,
what a great surprise, or what a great madness or what a person who want to make mad to his followers, a joke about himself,
and going one step forward
and now the same person robert spencer, try to proved that, muhammad did not exist,
is robert spencer is mad, or robert spencer is trying to make the reader mad,
