Musnad Ahmad 26:559

Waki' and Yazid narrated to us, Isma'il informed us, from Qays, from 'Abdullah, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "There is no envy except in two: A man whom Allah has given wealth, and he empowers him to spend it in the truth; and another whom Allah has given wisdom, so he judges by it and teaches it."
