The sunnah are the specific words, habits, practices, and silent approvals of The Prophet Muhammed (May peace and blessings be upon him)
The word Sunnah (سنة [ˈsunna], plural سنن sunan [ˈsunan], Arabic) is driven from the root (سن [sa-n-na] Arabic) meaning smooth and easy flow [of water] or direct flow path. The word literally means a clear and well trodden path.
In the discussion of the sources of religion, Sunnah denotes the practice of
Prophet Muhammad(P.B.U.H) that he taught and practically instituted as a teacher of the sharī‘ah and the best exemplar.1 According to Muslim belief, this practice is to be adhered to in fulfilling the divine injunctions, carrying out religious rites and molding life in accordance with the will of God. To institute these practices was, the Qur’ān states, a part of the Prophet’s responsibility as a Messenger of God. [Quran 3:164 , Quran 33:21]
The sunnah of
Muhammad includes his specific words, habits, practices, and silent approvals: It is significant because it addresses ways of life dealing with friends, family and government. Recording sunnah was an Arabian tradition and, once people converted to Islam, they brought this custom to their religion. The sunnah is consulted after referring to the Qur'an, if the issue is not addressed there.
