Position of Arabic language in jurisprudential rulings

The importance and position of Arabic language in Islamic knowledge is obvious. This research investigates the application of this Quran language in the field of Islamic Feqh. Feqh is based on Arabic language in lingual acts of worship, trades and rules. We intend to prove the need of feqh to Arabic language, which is distinct from the relation between the language and feqh in educational and research matters. The practices of praying, Talbieh in Hajj and the oaths are investigated for their use of Arabic. For trades, only the overall subject- the Arabic language- is discussed. It’s to be noted that the use of Arabic is a point of consensus for the Faqih when there is adequate ability, and in case of emergency or inability, there are other ways that have been mentioned. This is due to the importance of Arabic as the original language of Islam, integrated in religious duties for the followers.
