Islamic scholar in the context of Islamic state

Ijtihad (/ˌɪdʒtəˈhɑːd/ IJ-tə-HAHD; Arabic: اجتهاد ijtihād [ʔidʒ.tihaːd], lit. 'physical effort' or 'mental effort') is an Islamic legal term referring to independent reasoning by an expert in Islamic law, or the thorough exertion of a jurist's mental faculty in finding a solution to a legal question. It is contrasted with taqlid (imitation, conformity to legal precedent). According to classical Sunni theory, ijtihad requires expertise in the Arabic language, theology, revealed texts, and principles of jurisprudence (usul al-fiqh), and is not employed where authentic and authoritative texts (Qur'an and hadith) are considered unambiguous with regard to the question, or where there is an existing scholarly consensus (ijma). Ijtihad is considered to be a religious duty for those qualified to perform it. An Islamic scholar who is qualified to perform ijtihad is called a "mujtahid".

For the first five centuries of Islam, the practice of ijtihad continued in theory and practice among Sunni Muslims. It then first became subject to dispute in the 12th century. By the 14th century, development of classic Islamic jurisprudence or fiqh prompted leading Sunni jurists to state that the main legal questions in Islam had been addressed, and to call for the scope of ijtihad to be restricted. In the modern era, this gave rise to a perception amongst Orientalist scholars and sections of the Muslim public that the so-called "gate of ijtihad" was closed at the start of the classical era. While recent scholarship established that the practice of Ijtihad had never ceased in Islamic history, the extent and mechanisms of legal change in the post-formative period remain a subject of debate. Differences amongst the Fuqaha (jurists) prevented Sunni Muslims from reaching any consensus (Ijma) on the issues of continuity of Ijtihad and existence of Mujtahids. Thus, Ijtihad remained a key aspect of Islamic jurisprudence throughout the centuries. Ijtihad was practiced throughout the Early modern period and claims for ijtihad and its superiority over taqlid were voiced unremittingly.

Ibn Khaldun (27 May 1332 – 17 March 1406, 732–808 AH) was an Arab Islamic scholar, historian, philosopher, and sociologist. He is widely acknowledged to be one of the greatest social scientists of the Middle Ages, and considered by a number of scholars to be a major forerunner of historiography, sociology, economics, and demography studies.

His best-known book is the Muqaddimah or Prolegomena ("Introduction"), which he wrote in six months as he states in his autobiography. It later influenced 17th-century and 19th-century Ottoman historians such as Kâtip Çelebi, Mustafa Naima and Ahmed Cevdet Pasha, who used its theories to analyze the growth and decline of the Ottoman Empire. Ibn Khaldun interacted with Tamerlane, the founder of the Timurid Empire.

Haji Bektash Veli (Persian: حاجی بکتاش ولی, romanized: Ḥājī Baktāš Valī; Turkish: Hacı Bektaş Veli; Albanian: Haxhi Veli Bektashi; c. 1209–1271) was an Islamic scholar, mystic, saint and philosopher from Khorasan who lived and taught in Anatolia. His original name was Muhammad. He is also referred to as the "Sultan of Hearts" and the "Dervish of the Dervishes".

He is revered among Alevis for an Islamic understanding that is esoteric, rational and humanistic. He was one of the many figures who flourished in the Sultanate of Rum and had an important influence on the culture of Turkic nomads of Asia Minor.

Abū al-Ḥusayn Muslim ibn al-Ḥajjāj ibn Muslim ibn Ward al-Qushayrī an-Naysābūrī (Arabic: أبو الحسين مسلم بن الحجاج بن مسلم بن وَرْد القشيري النيسابوري; after 815 – May 875 CE / 206 – 261 AH), commonly known as Imam Muslim, was an Islamic scholar from the city of Nishapur, particularly known as a muhaddith (scholar of hadith). His hadith collection, known as Sahih Muslim, is one of the six major hadith collections in Sunni Islam and is regarded as one of the two most authentic (sahih) collections, alongside Sahih al-Bukhari.

Muhammad ibn Isa al-Tirmidhi (Arabic: محمد بن عيسى الترمذي, romanized: Muḥammad ibn ʿĪsā at-Tirmidhī; 824 – 9 October 892 CE / 209–279 AH), often referred to as Imām at-Termezī/Tirmidhī, was an Islamic scholar, and collector of hadith from Termez (early Khorasan and in present-day Uzbekistan). He wrote al-Jami` as-Sahih (known as Jami` at-Tirmidhi), one of the six canonical hadith compilations in Sunni Islam. He also wrote Shama'il Muhammadiyah (popularly known as Shama'il at-Tirmidhi), a compilation of hadiths concerning the person and character of the Islamic prophet, Muhammad. At-Tirmidhi was also well versed in Arabic grammar, favoring the school of Kufa over Basra due to the former's preservation of Arabic poetry as a primary source.

Malik ibn Anas (Arabic: مَالِك بْن أَنَس, romanized: Mālik ibn ʾAnas; c. 711–795), also known as Imam Malik, was a Muslim scholar, jurist, muhaddith and traditionalist who is the eponym of the Maliki school, one of the four schools of Islamic jurisprudence in Sunni Islam.

Born in Medina into the clan of Humayr which belonged to the Banu Taym of Quraysh, Malik studied under Hisham ibn Urwa, Ibn Shihab al-Zuhri, Ja'far al-Sadiq, Nafi ibn Sarjis and others. He rose to become the premier scholar of hadith in his day, Referred to as the Imam of Medina by his contemporaries, his views in matters of jurisprudence became highly cherished both in his own life and afterward, becoming the eponym of the Maliki school, one of the four major schools of Islamic jurisprudence. His school became the normative rite for Sunni practice in much of North Africa, al-Andalus (until the expulsion of medieval native Iberian Muslims), a vast portion of Egypt, some parts of Syria, Yemen, Sudan, Iraq, and Khorasan, and the prominent orders in Sufism, the Shadili and Tijani.

Abū al-Ḥasan ʻAlī ibn ʻAbdillāh ibn Jaʻfar al-Madīnī (778 CE/161 AH – 849/234) (Arabic: أبو الحسن علي بن عبد الله بن جعفر المديني) was a ninth-century Sunni Islamic scholar who was influential in the science of hadith. Alongside Ahmad ibn Hanbal, Ibn Abi Shaybah and Yahya ibn Ma'in, Ibn al-Madini has been considered by many Muslim specialists in hadith to be one of the four most significant authors in the field.

Yahya ibn Ma'in (Arabic: يحيى بن معين, romanized: Yaḥyā ibn Maʻīn; 774-847) was a classical Islamic scholar in the field of hadith. He was a close friend of Ahmad ibn Hanbal for much of his life. Ibn Ma'in is known to have spent all of his inheritance on seeking hadith to the extent he became extremely needy.

Mu'in al-Din Hasan Chishti Sijzi (Persian: معین الدین چشتی, romanized: Muʿīn al-Dīn Chishtī; 1 February 1143 – 15 March 1236), known reverentially as Khawaja Gharib Nawaz (Persian: خواجه غریب نواز, romanized: Khawāja Gharīb Nawāz), was a Persian Sayyid Islamic scholar and mystic from Sistan, who eventually ended up settling in the Indian subcontinent in the early 13th-century, where he promulgated the Chishtiyya order of Islamic mysticism. This particular Tariqa (order) became the dominant Islamic spiritual order in medieval India. Most of the Indian Sunni saints are Chishti in their affiliation, including Nizamuddin Awliya (d. 1325) and Amir Khusrow (d. 1325).

Having arrived in the Delhi Sultanate during the reign of the sultan Iltutmish (d. 1236), Muʿīn al-Dīn moved from Delhi to Ajmer shortly thereafter, at which point he became increasingly influenced by the writings of the Sunni Hanbali scholar and mystic ʿAbdallāh Anṣārī (d. 1088), whose work on the lives of the early Islamic saints, the Ṭabāqāt al-ṣūfiyya, may have played a role in shaping Muʿīn al-Dīn's worldview. It was during his time in Ajmer that Muʿīn al-Dīn acquired the reputation of being a charismatic and compassionate spiritual preacher and teacher; and biographical accounts of his life written after his death report that he received the gifts of many "spiritual marvels (karāmāt), such as miraculous travel, clairvoyance, and visions of angels" in these years of his life. Muʿīn al-Dīn seems to have been unanimously regarded as a great saint after his death.

European Islam, or Euro-Islam, is a hypothesized new branch of Islam that historically originated and developed among the European peoples of the Balkans (primarily Albania, Bosnia and Herzegovina, Kosovo, and European Turkey, but also in Bulgaria, Montenegro, and North Macedonia, countries with sizable Muslim minorities). These communities, alongside those in some republics of Russia, constitute a large population which constitute large populations of European Muslims. Historically significant Muslim populations in Europe include Azerbaijanis, Ashkali and Balkan Egyptians, Balkan Turks, Bosniaks, Böszörmény, Chechens, Circassians, Cretan Turks, Crimean Tatars, Gajals, Gorani, Greek Muslims, Ingush, Khalyzians, Kazakhs, Lipka Tatars, Muslim Albanians, Muslim Romani people, Pomaks, Torbeshi, Turks, Turkish Cypriots, Vallahades, Volga Tatars, Yörüks, and Megleno-Romanians from Notia today living in East Thrace, although the majority are secular.

The terms "European Islam" and "Euro-Islam" were originally introduced at a conference that took place in Birmingham in 1988, presided by Carl E. Olivestam, senior lecturer at Umeå University, and subsequently published in the Swedish handbook Kyrkor och alternativa rörelser ("Churches and Alternative Movements"). "European Islam" defines the ongoing debate on the social integration of Muslim populations in Western European countries such as France, Germany, the United Kingdom, and the Netherlands. There are three Islamic scholars who participate in the debate on "Euro-Islam": Enes Karić, Bassam Tibi, and Tariq Ramadan, who adopted the term in the second half of the 1990s but use it with different meanings. The foremost Western, Non-Muslim scholars of political science and/or Islamic studies involved in the debate on "Euro-Islam" are Jocelyne Cesari, Jørgen S. Nielsen, and Olivier Roy.

Rashīd Aḥmad ibn Hidāyat Aḥmad Ayyūbī Anṣārī Gangohī (12 June 1826 – 11 August 1905) was an Indian Deobandi Islamic scholar, a leading figure of the Deobandi movement, jurist and scholar of hadith, author of Fatawa-e-Rashidiya. His lineage reaches back to Abu Ayyub al-Ansari.

Along with Muhammad Qasim Nanautawi he was a pupil of Mamluk Ali Nanautawi. Both studied the books of hadith under Shah Abdul Ghani Mujaddidi and later became Sufi disciples of Haji Imdadullah. His lectures on Sahih al-Bukhari and Jami` at-Tirmidhi were recorded by his student Muhammad Yahya Kandhlawi, later edited, arranged, and commented on by Zakariyya Kandhlawi, and published as Lami al-Darari ala Jami al-Bukhari and Al-Kawakib al-Durri sharh Jami al-Tirmidhi.

The Great History (Arabic: التاريخ الكبير, romanized: al-Tārīkh al-Kabīr) is a book by ninth-century Islamic scholar Muhammad ibn Ismail al-Bukhari in the field of biographical evaluation (ʿilm ar-rijāl).

Petro-Islam is a neologism used to refer to the international propagation of the extremist and fundamentalist interpretations of Sunni Islam derived from the doctrines of Muhammad ibn Abd al-Wahhab, a Sunni Muslim preacher, scholar, reformer and theologian from Uyaynah in the Najd region of the Arabian Peninsula, eponym of the Islamic revivalist movement known as Wahhabism. This movement has been favored by the Kingdom of Saudi Arabia and the other Arab states of the Persian Gulf.

Its name derives from source of the funding, petroleum exports, that spread it through the Muslim world after the Yom Kippur War. The term is sometimes called "pejorative" or a "nickname".According to Sandra Mackey the term was coined by Fouad Ajami. It has been used by French political scientist Gilles Kepel, Bangladeshi scholar Imtiyaz Ahmed, and Egyptian philosopher Fouad Zakariyya, among others.

Imām Rabbānī Aḥmad ibn 'Abd al-Ahad al-Fārūqī al-Sirhindī Mūjaddīd al-Alf al-Thanī or simply known as Ahmad Sirhindi (1564 – 1624/1625) was an Indian Islamic scholar, Hanafi jurist, and member of the Naqshbandī Sufi order who lived during the era of Mughal Empire.

Ahmad Sirhindi opposed heterodox movements within the Mughal court such as Din-i Ilahi, in support of more orthodox forms of Islamic Law. His act of preserving and urging the practice of Islamic orthodoxy and challenging Akbar and later Jahangir by rejecting Din-i Ilahi has cemented his reputation among Sub-continent Muslims as a Mujaddid, or a "reviver".

Muhammad Marmaduke Pickthall (born Marmaduke William Pickthall; 7 April 1875 – 19 May 1936) was an English Islamic scholar noted for his 1930 English translation of the Quran, called The Meaning of the Glorious Koran. His translation of the Quran (usually anglicized as "Koran" in Pickthall's era) is one of the most widely known and used in the English-speaking world. A convert from Christianity to Islam, Pickthall was a novelist, esteemed by D. H. Lawrence, H. G. Wells, and E. M. Forster, as well as journalists, political and religious leaders. He declared his conversion to Islam in dramatic fashion after delivering a talk on 'Islam and Progress' on 29 November 1917, to the Muslim Literary Society in Notting Hill, West London.
