Islamic Jurisprudence: Customs and Usages/ Traditions prevailing at the time of Prophet Muhammad SAW

Islamic Fiqh recognizes customs that prevailed at the time of Muhammad but were not abrogated by the Qur'an or the tradition (called "Divine silence"). Practices later innovated are also justified, since Islamic tradition says what the people, in general, consider good is also considered as such by God. According to some sources, urf holds as much authority as ijma (consensus), and more than qiyas (analogical deduction). Urf is the Islamic equivalent of "common law".
