Persian migrants to South Asia, as influential bureaucrats and landholders, helped spread Shia Islam, forming some of
11088-730: The Persian contribution to this new Islamic civilization is of immense importance. The work of Iranians can be seen in every field of cultural endeavor, including Arabic poetry, to which poets of Iranian origin composing their poems in Arabic made a very significant contribution." While cultural influence used to radiate outward from Baghdad, after the Mongol destruction of the Abbasid Caliphate, Arab influence decreased. Iran and Central Asia, benefiting from increased cross-cultural access to East Asia under Mongol rule , flourished and developed more distinctively from Arab influence, such as
11232-557: The Quran and hadith. The classical theory of Islamic jurisprudence elaborates how scriptures should be interpreted from the standpoint of linguistics and rhetoric. It also comprises methods for establishing authenticity of hadith and for determining when the legal force of a scriptural passage is abrogated by a passage revealed at a later date. In addition to the Quran and sunnah, the classical theory of Sunni fiqh recognizes two other sources of law: juristic consensus ( ijmaʿ ) and analogical reasoning ( qiyas ). It therefore studies

11808-472: The actual wording, called matn . There are various methodologies to classify the authenticity of hadiths, with the commonly used grading grading scale being "authentic" or "correct" ( صحيح , ṣaḥīḥ ); "good" ( حسن , ḥasan ); or "weak" ( ضعيف , ḍaʻīf ), among others. The Kutub al-Sittah are a collection of six books, regarded as the most authentic reports in Sunni Islam . Among them

For
12096-508: The ancients" or "rational sciences", from Islamic religious sciences. Sciences of the former type flourished for several centuries, and their transmission formed part of the educational framework in classical and medieval Islam. In some cases, they were supported by institutions such as the House of Wisdom in Baghdad, but more often they were transmitted informally from teacher to student. The University of Al Karaouine , founded in 859 AD,
12240-507: The application and limits of analogy, as well as the value and limits of consensus, along with other methodological principles, some of which are accepted by only certain legal schools. This interpretive apparatus is brought together under the rubric of ijtihad , which refers to a jurist's exertion in an attempt to arrive at a ruling on a particular question. The theory of Twelver Shia jurisprudence parallels that of Sunni schools with some differences, such as recognition of reason ( ʿaql ) as
12384-420: The attempts to impose a caliphal writ in matters of religious orthodoxy ultimately failed. This controversy persisted until al-Ash'ari (874–936) found a middle ground between Mu'tazilite rationalism and Hanbalite literalism, using the rationalistic methods championed by Mu'tazilites to defend most substantive tenets maintained by ahl al-hadith . A rival compromise between rationalism and literalism emerged from
12528-838: The beginning of the compilation of the Quran. The Caliph Umar ibn Abd al-Aziz set up the committee, The Seven Fuqaha of Medina , and Malik ibn Anas wrote one of the earliest books on Islamic jurisprudence, the Muwatta , as a consensus of the opinion of those jurists. The Kharijites believed there was no compromised middle ground between good and evil, and any Muslim who committed a grave sin would become an unbeliever. The term "kharijites" would also be used to refer to later groups such as ISIS . The Murji'ah taught that people's righteousness could be judged by God alone. Therefore, wrongdoers might be considered misguided, but not denounced as unbelievers. This attitude came to prevail into mainstream Islamic beliefs. The Umayyad dynasty conquered
12672-400: The boundaries of the schools became clearly delineated, the authority of their doctrinal tenets came to be vested in a master jurist from earlier times, who was henceforth identified as the school's founder.

13248-456: The decrease in Arab influence after the Mongol destruction of the Abbasid Caliphate. The Muslim Mongol Khanates in Iran and Central Asia benefited from increased cross-cultural access to East Asia under Mongol rule and thus flourished and developed more distinctively from Arab influence, such as the Timurid Renaissance under the Timurid dynasty . Nasir al-Din al-Tusi (1201–1274) proposed

13536-470: The early Abbasid era, scholars such as Muhammad al-Bukhari and Muslim ibn al-Hajjaj compiled the major Sunni hadith collections while scholars like Al-Kulayni and Ibn Babawayh compiled major Shia hadith collections. The four Sunni Madh'habs , the Hanafi, Hanbali, Maliki, and Shafi'i, were established around the teachings of Abū Ḥanīfa , Ahmad ibn Hanbal , Malik ibn Anas and al-Shafi'i . In contrast,
13680-406: The end of the ninth to the end of the eleventh century. The era after this period is conventionally known as the "age of decline". A survey of literature from the nineteenth century onwards demonstrates that the decline theory has become the preferred paradigm in general academia. The various Quranic injunctions and Hadith (or actions of Muhammad ), which place values on education and emphasize
13824-637: The equivalent of professional athletes today. The House of Wisdom was a library established in Abbasid -era Baghdad , Iraq by Caliph al-Mansur in 825 modeled after the academy of Jundishapur . During this period, the Muslims showed a strong interest in assimilating the scientific knowledge of the civilizations that had been conquered.

Christians , especially
13968-577: The essence of objects flows into the eyes. Alhazen correctly argued that vision occurred when light, traveling in straight lines, reflects off an object into the eyes.

14544-663: The importance of acquiring knowledge, played a vital role in influencing the Muslims of this age in their search for knowledge and the development of the body of science. The Islamic Empire heavily patronized scholars. The money spent on the Translation Movement for some translations is estimated to be equivalent to about twice the annual research budget of the United Kingdom's Medical Research Council . The best scholars and notable translators, such as Hunayn ibn Ishaq , had salaries that are estimated to be
14688-738: The institution, and it placed its holder within a genealogy of scholars, which was the only recognized hierarchy in the educational system. While formal studies in madrasas were open only to men, women of prominent urban families were commonly educated in private settings and many of them received and later issued ijazas in hadith studies, calligraphy and poetry recitation. Working women learned religious texts and practical skills primarily from each other, though they also received some instruction together with men in mosques and private homes. Madrasas were devoted principally to study of law, but they also offered other subjects such as theology, medicine, and mathematics. The madrasa complex usually consisted of

14976-652: The majority. Caliph Al-Mu'tasim carried out inquisitions , with the traditionalist Ahmad ibn Hanbal notably refusing to conform to the Muʿtazila idea that the Quran was created rather than being eternal , which resulted in him being tortured and kept in an unlit prison cell for nearly thirty months. However, other schools of speculative theology – Māturīdism founded by Abu Mansur al-Maturidi and Ash'ari founded by Al-Ash'ari – were more successful in being widely adopted. Philosophers such as Al-Farabi , Avicenna and Averroes sought to harmonize Aristotle's ideas with

Al-Shafi'i codified a method to determine the reliability of hadith. During
16416-564: The planets. One of the first to criticize this model was Ibn al-Haytham , a leader of physics in the 11th century in Cairo. Then in the 13th century Nasir al-Din al-Tusi constructed the Maragha Observatory in what is today Iran. Al-Tusi found the equant dissatisfying and replaced it by adding a geometrical technique called a Tusi-couple , which generates linear motion from the sum of two circular motions. Then, Ibn al-Shatir who
16560-518: The poor, foreigners, and slaves like the first muezzin Bilal ibn Rabah al-Habashi . The Meccan elite felt Muhammad was destabilizing their social order by preaching about one God and giving questionable ideas to the poor and slaves because they profited from the pilgrimages to the idols of the Kaaba.
