3. PRACTICE
The third way of preservation of the Sunnah was to bring it into practice.
The knowledge of Sunnah was not merely a theoretical knowledge, nor were the teachings of the Holy Prophet (SAWS) merely philosophical. They related to practical life. The Holy Prophet (SAWS) did not confine himself to giving lessons and sermons only; he also trained his companions practically. Whatever they learnt from the Holy Prophet (SAWS) they spared no effort to bring it into actual practice. Each companion was so enthusiastic in practicing the Sunnah of the Holy Prophet (SAWS), that he tried his best to imitate even his personal habits.
