Mujtahid in the context of "Ayatollah"

Fiqh ([fiːk]; Arabic: فقه [fiqh]) is the term for Islamic jurisprudence. Fiqh is often described as the style of human understanding, research and practices of the sharia; that is, human understanding of the divine Islamic law as revealed in the Quran and the sunnah (the teachings and practices of the Islamic prophet Muhammad and his companions). Fiqh expands and develops Shariah through interpretation (ijtihad) of the Quran and Sunnah by Islamic jurists (ulama) and is implemented by the rulings (fatwa) of jurists on questions presented to them. Thus, whereas sharia is considered immutable and infallible by Muslims, fiqh is considered fallible and changeable. Fiqh deals with the observance of rituals, morals and social legislation in Islam as well as economic and political system. In the modern era, there are four prominent schools (madh'hab) of fiqh within Sunni practice, plus two (or three) within Shi'a practice. A person trained in fiqh is known as a faqīh (pl.: fuqaha).

Figuratively, fiqh means knowledge about Islamic legal rulings from their sources. Deriving religious rulings from their sources requires the mujtahid (an individual who exercises ijtihad) to have a deep understanding in the different discussions of jurisprudence.

Al-Ghazali (c. 1058 – 19 December 1111), archaically Latinized as Algazelus, was a Shafi'i Sunni Muslim scholar and polymath. He is known as one of the most prominent and influential jurisconsults, legal theoreticians, muftis, philosophers, theologians, logicians and mystics in Islamic history.

He is considered to be the 11th century's mujaddid, a renewer of the faith, who, according to the prophetic hadith, appears once every 100 years to restore the faith of the Islamic community. Al-Ghazali's works were so highly acclaimed by his contemporaries that he was awarded the honorific title "Proof of Islam" (Ḥujjat al-Islām). Al-Ghazali was a prominent mujtahid in the Shafi'i school of law.

Taqlid (Arabic: تقليد, romanized: Taqlīd) is a term used in Islamic jurisprudence to denote the conformity of one person to the teaching of another. As such, the person who performs taqlid is termed muqallid. The definite meaning of the term varies depending on context and age. Classical usage of the term differs between Sunni Islam and Shia Islam. Sunni Islamic usage designates the unjustified conformity of one person to the teaching of another, rather than the justified conformity of a layperson to the teaching of a mujtahid (a person who is qualified for independent reasoning). Shia Islamic usage designates general conformity to the teaching of a mujtahid, and there is no negative connotation. The discrepancy corresponds to differing views on the Shia Imamate and Sunni imams.

In contemporary Salafi usage, taqlid is often portrayed in a negative light and translated as "blind imitation". This refers to the perceived stagnation of independent effort (ijtihad) and uncritical imitation of traditional religious interpretation by the religious establishment in general.

Mirza Mohammad Torbati ( میرزا محمد تربتی), better known as Mushtaq Ali Shah (مشتاق علی شاه) was a Sufi mystic and a Muslim musician who was martyred for playing his instrument in 1792. Shah was a member of the Nimatullahi Order of Sufis, and a majdhoub, who attracted Ismailis and others when he sang and played his setar. Majdhoubs were "spiritual men whose mental faculties are as it were paralyzed or confused by the effect of the Divine attraction" and got "divinely intoxicated" when they performed. Shah disregarded the conventions of his day, and was accused of "singing and playing the call to prayer at the Jum'ah Masjid on 27th Ramadan (19 May) 1792, and was stoned to death.

In another account, he was accused of "reciting the Qur'an with the sound of a setar" by Mullah Mohammad Taqi (ملا محمد تقی), a mujtahid."
