Taliban – took place, resulting in a war on terror launched against the Taliban. The sequence of events of the 20th century has led to resentment in some quarters of the Sunni community due to the loss of pre-eminence in several previously Sunni-dominated regions such as the Levant, Mesopotamia, the Balkans, the North Caucasus and the Indian sub continent. The latest attempt by a radical wing of Salafi-Jihadists to re-establish a Sunni caliphate was seen in the emergence of the militant group ISIL, whose leader Abu Bakr al-Baghdadi is known among his followers as caliph and Amir-al-mu'mineen, "The Commander of the Faithful". Jihadism is opposed from within the Muslim community (known as the ummah in Arabic) in all quarters of the world as evidenced by turnout of almost 2% of the Muslim population in London protesting against ISIL. Following the puritan approach of Ibn Kathir, Muhammad Rashid Rida, etc. many contemporary Tafsir (exegetic treatises) downplay the earlier significance of Biblical material (Isrā'iliyyāt). Half of the Arab commentaries reject Isrā'iliyyāt in general, while Turkish tafsir usually partly allow referring to Biblical material. Nevertheless, most non-Arabic commentators regard them as useless or not applicable. A direct reference to the Israeli–Palestinian conflict could not be found. It remains unclear whether the refusal of Isrā'iliyyāt is motivated by political discourse or by traditionalist thought alone. The usage of tafsir'ilmi is another notable characteristic of modern Sunni tafsir. Tafsir'ilmi stands for alleged scientific miracles found in the Qur'an. In short, the idea is that the Qur'an contains knowledge about subjects an author of the 7th century could not possibly have. Such interpretations are popular among many commentators. Some scholars, such as the Commentators of Al-Azhar University, reject this approach, arguing the Qur'an is a text for religious guidance, not for science and scientific theories that may be disproved later; thus tafsir'ilmi might lead to interpreting Qur'anic passages as falsehoods. Modern trends of Islamic interpretation are usually seen as adjusting to a modern audience and purifying Islam from alleged alterings, some of which are believed to be intentional corruptions brought into Islam to undermine and corrupt its message. Adherents Sunnis believe the companions of Muhammad to be reliable transmitters of Islam, since God and Muhammad accepted their integrity. Medieval sources even prohibit cursing or vilifying them. This belief is based upon prophetic traditions such as one narrated by Abdullah, son of Masud, in which Muhammad said:
