“Terrorism is caused by those groups or individuals who resort to killing and wreaking havoc and destruction… As the Prophet mentioned concerning the signs of the end of time, the spread of ‘al-Harj’ (riotous killing). The meaning of ‘al-Harj’ is killing and the increase of the spilling blood, which is all from the signs of the end of time. To the extent that the one killing will not know, why he is killing and the one that was killed will not know why he/she was killed. Islam is free from this riotous killing, free from this terrorism and free from this kind of corruption. (Shaykh Muhammad ibn Abdul-Wahhaab al-Aqeel)
