Read what Sayaydi Rasul Allah (sm) has warned about these Khawarij. We are forbidden to treat these Khawarij as friends or brothers. We are asked to kill these dogs of hell where ever we find them. There is a reason why Sayaydi Rasul Allah (sm) has ordered us to eliminate these fitnah! These Khawarij bring a bad name to Shariat of Rasul Allah (sm) and are frauds exploiting the name of Islam and shariat. Having mercy upon these dogs of hell is showing cruelty on Ummah of Rasul Allah (sm).
