Principles of Islamic jurisprudence


Principles of Islamic jurisprudence otherwise known as Uṣūl al-fiqh (Arabic: أصول الفقه‎‎) is the study and critical analysis of the origins, sources, and principles upon which Islamic jurisprudence is based.

Traditionally four main sources (Qur’an, Sunnah, consensus (Ijma), analogical reason (Qiyas)) are analysed along with a number of secondary sources and principles.

The main subject areas of discussion are these:

Uṣūl al-fiqh comprises the conjunction of two Arabic terms, uṣūl and fiqh. Uṣūl is derived from the root letters hamza, sad and lām which refers to basis. Fiqh linguistically refers to knowledge, deep understanding or comprehension.

Technically the term is used to refer to the body of evidences and principles that Islamic jurists utilise to provide solutions to problems.

The science of uşūl al-fiqh is a science in which such rules whose results are placed in ways of deduction of juristic precepts are discussed. For instance, performing the prayers (şalāt) is mandatory in Islam, and this Qur’ānic verse proves that obligation: “And that perform the prayers” (6, 72). However, denotation of the verse is dependent upon the imperative, like “perform” in that verse, being apparent in the obligation on the one hand and Qur’ānic apparent meanings being authoritative on the other. Those two issues are dealt with in the science of uşūl al-fiqh. Now, when the jurist learns through this science that the imperative is apparent in the obligation and that the Qur’ānic apparent meanings are authoritative proofs, he can infer from the said verse that the prayers is mandatory.

The Qur'an has always been regarded as the primary legal source of Islam, the speech of Allah. It has been transmitted through numerous chains (mutawatir) and proven through rational argument.

This has been supplemented by further revelation termed sunnah. It comprises explanations from Muhammad in terms of his speech, actions and silences which have been historically compiled and verified through chains of narrations called hadiths. Sunnah is referred to for elaboration of the Quran or for clarification of a matter that is not mentioned in the Quran and is second in prioritisation to Quran.
