Hadith

Narrated by Ibn Masud : I heard the Prophet (SAWS) saying, "There is no envy except in two: a person whom Allah has given wealth and he spends it in the right way, and a person whom Allah has given wisdom (i.e. religious knowledge) and he gives his decisions accordingly and teaches it to the others."
