ANSWER:

Such envy was mentioned in the hadeeth:

There should be no envy (hasad) except between two people, a man to whom Allaah has given (knowledge of) the Qur’aan, so he recites it night and day, and a man to whom Allaah has given wealth, so he spends it (in good deeds) night and day.”  (narrated by Muslim, 815)

QUESTION: Is there something called GOOD envy like envying the reward somebody will inshallah get frm Allah.
