Abu Huraira reported God’s messenger as saying, “If anyone
acquires knowledge of things by which God’s good pleasure is sought,
but acquires it only to get some worldly advantage, he will not experience the ‘arf, i.e. the odour, of paradise on the day of resurrection.”
Ahmad, Abu Dawud and Ibn Majah transmitted it.
Ka'b b. Malik reported God’s messenger as saying, “If anyone
seeks knowledge to use it in vying with the learned, or disputing with
the foolish, or to attract men’s attention to himself, God will bring him
into hell.” Tirmidhi transmitted it, and Ibn Majah transmitted it from
Ibn ‘Umar.
Narrated 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:
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.
Abu Huraira reported God’s messenger as saying, “He who is
asked about something he knows and conceals it will have a bridle of fire
put on him on the day of resurrection.” Ahmad, Abu Dawud and
Tirmidhi transmitted it, and Ibn Majah transmitted it from Anas.
