Abu Hazim, Salma bin Dinar سلمة بن دينار أبو حازم الأعرج · Knowledge (Kitab Al-Ilm)

I heard the Messenger of Allah (ﷺ) say: May Allah brighten a man who hears a tradition from us, gets it by heart and passes it on to others. Many a bearer of knowledge conveys it to one who is more versed than he is; and many a bearer of knowledge is not versed in it.
