As a phenomenon, jurisprudential revisions implemented by contemporary jihadist Salafist groups have garnered the attention of observers and analysts in the recent past. This is largely because these revisions emerged from within jihadist Salafist groups themselves following their entry into violent and armed conflicts with all political regimes, ranging from Arab and Islamic non-Arab regimes to powerful non-Islamic countries, particularly the United States and Western countries. Such conflicts have been established on an ideology based on takfir (labeling other Muslims as kuffar or disbelievers) and the violent combat strategy adopted by these groups during the past decades. These groups have posed a major challenge for Arab and Islamic political regimes. In addition, large numbers of Arabs and Muslims have fallen victim to these clashes, exceeding the number of victims of the Arab-Israeli wars.
