I read in the Islamic history that prophet Muhammed sent a (warrior) to promote Islam for some people. After that warrior (his name was Khalid Waleed) did his job, some of those people did not show very good faith in Islam and therfore the warrior KILLED many of them and captured others. He later tried to KILL those who were captured. When prophet Muhammed knew about those crimes, all what he did is that he denounced it and announced for people that he did not order that warrior to do what he has done. That is it! After the war crimes committed (killing people with no reason and trying to kill prisoners), there was no trial for the warrior, no further denouncement. NOTHING. Actually, prophet Muhammed sent that warrior over and over again to fight for Islam! Was not prophet Muhammed supposed to at least dismiss that warrior from leading more Islamic armies?
