According to the Encyclopaedia of Islam, Sunna can be conceptually defined as the consensually accepted methodology and the way of life in Islam as prescribed and practiced by Prophet Muhammad and his companions. In addition, Sunna has been regarded at the highest degree right after the Quran in accordance to shari’a law under mahsab Shafi’i which are still in practice today. However, the perception of Sunna has been debated and transformed from the olden days with subtle differences in interpretation. In the olden days, sunna was conceptualized as the behavior of the preceding generation which includes the good and the bad. However, after the passing of Prophet Muhammad, sunna act as a reminder in the Islamic community and was used as rules and guidelines to assist them through their difficulties from matters within oneself up to matters in politics. However, being human, people tend to include their personal opinions and judgements causing a change in context through these translations. This act was shun upon by ulama(body of Islamic scholars), hence, a procedure to evaluate the authenticity of the sunna was established. This procedure is called isnad. After the establishment of isnad, there was a progressive increase in sunna. This was partly due to the hadith which states that those who pave the way of good sunna will be rewarded and those who damages the concept of sunna will carry the burden along with those who followed him. Sunna in this era is in a fundamental point of controversies among scholars. Some scholars hypothesize that to evaluate the authenticity of hadith; it has to be written as oral transmission is not trustworthy, hence, questioning the precedence of sunna.
