The evaluation of concepts of marouf and urf (tradition) in Koran according to the Islamic jurisprudence (fiqh)

Tradition is the main distinguishing character of a society. In this context, Islam claiming to be a universal religion can not feel itself freed from this reality. Human experience and tradition are also important for it. The rules of Islam dos not only make rules about belief and ethic but also establishes dynamic rules whose contents can be changeable according to time and condition. In other words, religion depends on the rules from Koran and it also depends on traditions.The concept of marouf is a good example showing that religion depends on tradition. Maoruf which passes in 39 places in Koran, it means ?suitable to religion ?and ?suitable to custom and tradition? especially in family laws. If the related passages from Koran are evaluated from this point of view, this become a powerful evidence for tradition as a supply of Islamic law and the related subjects make the examples of tradition in Koran.While the Islamic jurists (faqihs) work on related passages and subjects, they make attributions to tradition directly or indirectly and they used tradition as a secondary evidence while they try to prove the degreess. Moreover, tradition became a legal ground for law system, as it in the example of mecelle (moslim code of legislation) and in the decree of family law.Keywords: nass, tradition, urf (custom), marouf
