Ibn Mas'ud reported God’s messenger as saying,“God brighten a man who hears what I say, gets it by heart, retains it, and passes it on to others! Many a bearer of knowledge is not versed in it, and many a bearer of knowledge conveys it to one who is more versed than he is. There are three things on account of which no rancour enters a Muslim's heart:sincere action for God’s sake, good counsel to Muslims, and hold- ing fast to their community, for their invitation includes those who are beyond them.”Shafi‘i transmitted it, also Baihaqi in al-Madkhal.
