A man for Yemen his name is Khawlan was advised by his friend to talk to Wahb Ibn Munabbih regarding a command reached him from the Khawarij leader in Sanaa, once they meet Wahb Ibn Munabbih, he said to them: “O you inexperienced ones, beware of the Harooraa. Do not allow them to submit you to their devious views. For verily, they are scabies of this Ummah.” he continued:  “‘O Dhoo Khawlān, do you want to be from the Harooraa (Khawarij) in your old age now, declaring that those who are better than you are lost? What will you say tomorrow when Allah takes you? ‘He who you testified against, Allah has attested to the faith of, he who you attested to his disbelief. And Allah has witnessed the guidance of he who you have witnessed his deviance, so where do you fall if your opinions and testimonies are contrary to Allah’s Decree and Testimony? (Abdus-Salām Ibn Burjiss: Munaasihatul-Imām Wahb Ibn Munabbih)
