Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: "Envy (i.e., permissible envy) is only for two types of people: one is the person whom Allah Almighty has granted wealth and then given him the ability to spend that wealth in the way of truth, or the person whom Allah Almighty has granted wisdom and he judges according to it or teaches it."
