When the Sinful and the Rabble Take Knowledge

ʿAbdullāh b. Masʿūd – Allāh be pleased with him – said:

The people will not cease to be well as long as they take knowledge from their seniors. When they take it from their juniors and their bad people, they will be destroyed.

Ibn ʿAbd Al-Barr, Jāmiʿ Bayān Al-ʿIlm article 1057.
