Knowledge (Kitab Al-Ilm)

Dawud :: Book 25 : Hadith 3656

Narrated AbuHurayrah:

The Prophet (peace_be_upon_him) said: If anyone acquires knowledge of things by which Allah'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.
