My apologies, but if we say our prophet cant bear criticism or insults and demanded the person be killed, one can question if he he was really a mercy for the world?
I also dont get how blasphemy can apply to non-muslims. Non-msulims by definition dont believe in prophet mohammad which also means they think prophet was a lier. So all non-muslims are blasphemers? what kind of a non-sense rule is that?
Thirdly in many books I have read someone misbehaved with the prophet and his sahaba asked prophet if he allows then they can take the person to task. Question is, why sahaba bothered to ask for prophet's permission? kia onn mein ghairat kee kamee thee?
