In the name of Allah, Most Gracious, Most Merciful.
Narrated Amr ibn Awf (may Allah be pleased with him): ‘The Prophet (SAWS) said to Bilal ibn Al-Hareth: “Take into consideration.” Bilal said: “What should I take into consideration Messenger of Allah?” The Prophet (SAWS) said: “Verily, he that revives a Sunna (a practice) of mine that people have neglected after my death, would have its reward and a reward equal to those who acted upon it, without decreasing theirs by aught. And he that innovates an evil practice that Allah and His Messenger (SAWS) do not approve, would have its punishment and a punishment equal to the punishment of those who acted upon it, without decreasing theirs by aught.'” (At-Termizi)
SAWS: May Allah exalt his mention and protect him from imperfection
