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.
Abu Sa'id al-Khudri reported God’s messenger as saying, “A believer will never be satisfied with the good he hears till he reaches
paradise.” Tirmidhi 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.
Sakhbara al-Azdi reported God’s messenger as saying, “If anyone
seeks knowledge, it will be an atonement for past sins.” Tirmidhi and
Darimi transmitted it, Tirmidhi saying that this is a tradition whose
isnad is weak, and that Abu Dawud the transmitter is declared to be
weak.
