It is narrated from Imam Ridha/Reza (AS) who said:

God bless the one who revives our command (traditions of Ahlul Bait (AS)). A person asked: How your commands are revived? Imam (AS) replied: Learn our instructions, sciences and culture and teach them to others. Because if people hear and learn about the benefits of our sayings, will follow Ahlul Bait (AS) [1].
