The Role of Common Parlance in Ibn Idrīs's Jurisprudence

Each person’s style of thought and cognition is formed in the frame of time and place conditions in a way affecting his deductions. Changes and improvements of jurisprudence are caused by this effect. Common parlance has gained lots of attention by jurists since many years ago. Ibn Idrīs’s full understanding of his time‚ knowing common parlance‚ tending to solve problems, and stating the affected sentences had him try to break the condition of dullness and inertia governing jurisprudence as a bold jurist and establish a new jurisprudence. He could show the role of time and place in the jurisprudent changes by describing his time as a period of sterility of reasons and exhaustion of minds and objecting to his ancestors’ opinions. According to him‚ common parlance is an action which is common among people and should be continued. It contains the domain of action and words. He has mentioned two types of applications: the independent one such as detection of sentences and instrumental one for common parlance. The origins of these common parlances are different.
