Ummmm .... I think the radical Muslims DO put others on trial. Infidels and all that. I would guess that Muslim pretenders qualify for the "infidel" label. It is an impermisible exercise of ability, for humans to kill other humans in the name of religion. The victim of such travesty will get his just reward, whatever it is. As will the perpetrator.
Oh yes. But does it happen that Muslims are put on trial and asked to deny their god or else suffer death? If so, does their death qualify as martyrdom in the strict sense?
