Sayyiduna ‘Urfaajah bin Shuraih Ashja‘i (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings of Allah be upon him) say:“Soon after me there will be various kinds of tribulations, so if you see a person who separates himself from the (Muslim) community or wants to create division among the Ummah of Muhammad (peace and blessings of Allah be upon him) while they are united, then kill him wherever he may be. Indeed, Allah’s hand is over the community, and indeed, Satan is with the one who separates himself from the (Muslim) community.”
