أَلاَ وَقَدْ أَمَرَنِيَ اللهُ بِقِتَالِ أَهْلِ الْبَغْي وَالْنَّكْثِ وَالْفَسَادِ فِي الاَْرْضِ، فَأَمَّا النَّاكِثُونَ فَقَدْ قَاتَلْتُ، وَأَمَّا الْقَاسِطُونَ فَقَدْ جَاهَدْتُ، وَأَمَّا الْمَارِقَةُ فَقَدْ دَوَّخْتُ
Beware! Surely Allah has commanded me to fight those who rebellion or break their pledge or create trouble in the land. As regarding pledge-breakers, I have fought them. As regarding those who shrunk from the truth, I have waged a holy war against them. And as regarding those who have abandoned the creed, I have put them in (serious) disgrace
