Repelling the Evil Before it Takes Place is Easier than Repelling it After it has Happened

Al-Imam Abu Haneefah (may Allah have mercy upon him) stated:

“It is befitting for the Imam (the Muslim ruler), when the news reaches him that the Khawaarij are preparing for combat, to seize them and imprison them in order that they leave this off. This is due to the fact that repelling the evil before it takes place is easier than repelling it after it has happened.”
