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.
Ahmad, Tirmidhi, Abu Dawud, Ibn Majah and Darimi transmitted it from
Zaid b. Thabit, but Tirmidhi and Abu Dawud did not mention, “There
are three things on account of which no rancour enters..." to the end.
