It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "May Allah Almighty keep fresh and radiant the person who heard a hadith from us and then conveyed it (to others) exactly as he heard it, for often the one to whom something is conveyed retains and understands it better than the one who heard it."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Huraym and Ja'far (may Allah have mercy on them both) except Ishaq (may Allah have mercy on him)."
