The Arabic term for jurisprudence (fiqh) literally means: knowledge about something and understanding it; being clever.
Fiqh’s literal definition does not only mean understanding a word, instead it is a deep knowledge about it. Fiqh has been used in the Qurān in this meaning:
لَهُمْ قُلُوبٌ لاَّ يَفْقَهُونَ بِهَا
They have hearts wherewith they understand not.
Figuratively, fiqh means: knowledge about Islamic legal rulings from their sources. So, fiqh’s figurative definition is taken from its literal one in the sense that deriving religious rulings from their sources necessitates the mujtahed to have a deep understanding in the different discussions of jurisprudence. He must look deep down into a matter and not suffice himself with just the apparent meaning. A person who only knows the appearance of a matter is not a faqīh.
The subject of thinking deeply (tafaquh) about religion has been repeatedly mentioned in the Qurān and traditions transmitted from the prophet (s) and the Imāms (a). What is taken from them, on a whole, is that Islam wants man to deeply understand religion. Of course, this understanding covers such subjects as Islamic theology, Islamic ideology, ethics, Islamic upbringing, the Islamic social system, worship, religious rulings and manners that one must have in his individual and social life. The term ‘fiqh’ has become popular amongst Muslims since the second century after the great migration to mean Islamic jurisprudence or the art of deriving religious rulings from their sources. It has obtained the following meaning: a precise and deep understanding and ability to derive religious rulings from their sources.
The Meaning of Fiqh
Nowadays, the term fiqh is generalized to mean Islamic sciences or Islamic rulings in the broad sense. The broad meaning of Islamic rulings is broken up into three fundamental categories:
1. Theology; what is obligatory for a mukalaf to believe about Allah, his angels, books, messengers and the Day of Judgment.
2. Ethics; the positive traits that a mukalaf must obtain and the negative traits that he must stay away from.
3. Actions; the actions that a mukalaf must perform.
This is proved by the tradition from the prophet (s) who said: “Whoever wants Allah to treat him favorably must have a deep understanding (yafaqahu) in religion.”)
Here, the word fiqh is used in its general sense, synonymous of Islam.
When the different sciences are categorized the term fiqh is used to mean the Islamic rulings regarding one’s actions.
Fiqh, in its specific meaning and what is discussed in books of fiqh, includes everything that has to do with all aspects of man’s life. Everything that is studied today including foundational laws, city management, family relations, individual actions, management, politics, etc is found in the different sections of fiqh.
Shari’ah And Fiqh
Sharī‛ah encompasses what was decreed in the time of prophethood found in the Qurān and prophetic traditions.
Fiqh is what has been gained from the efforts of scholars after the prophet’s (s) demise.
