'disorder' is disobedience against Allah and his will- it includes breaking ties with Muslim kith and kin (apostasy). Sunan Abu Dawud (one of that hadith collections about the lives of Muhammed) confirms that the required punishment for fasad (mischief or disorder) is execution or crucifixion. According to some, in the eyes of certain Muslims all non-Muslims who reject Allah and Islam are “spreading corruption”(are thus enemies of Islam and cannot be innocent) and are legitimate targets to be killed. See Quran 5.33: 'Those that make war against God and His apostle and spread disorder in the land shall be slain and crucified or have their hands and feet cut off on alternate sides, or be banished from the land'.

August 2017 (Month video was uploaded): Terrorist Murders:
Islamic: 673 murders
Communist: 16 murders
Far right: 1 murder

btw the Imam should have said 'unless it is be for murder or spreading disorder/mischief in the land'

see Quaran 5.32 "... He who kills a soul unless it be (in legal punishment) for murder or for causing disorder and corruption on the earth will be as if he had killed all humankind..."

Shame he couldn't get it out quite right: changes the meaning somewhat. Probably an honest mistake ;)
