What is meant by Sunnah:
Sunnah is an Arabic word that means habit or usual practice. The Muslim usage of this term refers to the sayings and living habits of Muhammad (صلي الله عليه وسلم).
Recording sunnah was a tradition, and once people converted to Islam, they brought the tradition to the religion.
The Sunnah of Muhammad (صلي الله عليه وسلم) includes his specific words, habits, practices, and silent approvals. This is significant to the spirituality of Islam because it addresses ways of life dealing with friends, family, and government and should be followed by all Muslims.
