Envy to attain good characters

Ibn Mas'ood Radhiya Allahu anhu said that RasulAllah salla Allahu alayhi wa sallam said, "Let there be no envy except in two things; a man to whom Allah gave wealth and guided him to spend it in a righteous way and a man to whom Allah gave wisdom and he acts wisely and teaches it to others."
(Sahih Bukhari and Muslim)

Lessons:
-Shows importance of spending your wealth in the way of Allah, and to please Him alone. We will be questioned about each and every penny. And this is the difference between the rich and the poor. The poor will not be questioned as much as the one who Allah had blessed with wealth. We should always remember that the wealth we have is a trust from Allah SWT, and that Allah has given it to us so that we give to others, and spend on good things. Possession of wealth is a big responsibility.
-Also shows the importance of seeking beneficial knowledge. The difference between knowledge and wisdom is that one can have knowledge and still not have wisdom if he does not act according to it. Da'wah (teaching others) is a very important branch of the duties of a Muslim.
- Envy is not a good quality to possess. But still, it is allowed to be envious for the above reasons, in a healthy manner, that will encourage us to excel in both these fields.
