Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: People will remain righteous and holding firm (to the teachings of the religion) as long as knowledge comes to them from the Companions of Muhammad (peace and blessings be upon him) and from their elders. And when knowledge comes to them from their juniors, they will be destroyed.
Al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat, and its narrators have been declared trustworthy.
