Yes, the Sunnah, the practice and example of the Prophet (peace be upon him), is the second authority for Muslims. A Hadith is a reliably transmitted report of what the Prophet (peace be upon him) said, did, or approved. Belief in the Sunnah is part of the Islamic faith. Examples of the Prophet’s sayings The Prophet (peace be upon him) said: ‘God has no mercy on one who has no mercy for others.’ ‘None of you truly believes until he wishes for his brother what he wishes for himself.’ ‘Powerful is not he who knocks the other down, indeed powerful is he who controls himself in a fit of anger.’ (From the Hadith collections of Bukhari, Muslim, Tirmidhi and Baihaqi.)
