A summary of the concepts held by the Ahl al-Sunnah. Certain terrorist groups within the Islamic world and their negative impact. We do not deny in any way the existence of certain terrorist groups in the Islamic world throughout history and across the ages, up to our present time. However, they have always been groups that deviated from the methodology of the Ahl al-Sunnah wal-Jama'ah. They do not belong to it, even in form or in their call. For in the past, the Khawarij and the esoteric Rawafid emerged. Such as the sect of the Assassins from among the Ismailis and the Qarmatians. All of these and those like them— The scholars of the Ahl al-Sunnah would warn against them and clarify their errors and misguidance.
