From the mistakes of some of the Muslims is that they fall into Jealousy and Envy. They are to dislike that which Allah has blessed one of his servants with. It is not just a desire for the stopping of that which Allah (‘azawajala) has blessed other than him with, rather it is absolute dislike of the person for that which Allah has blessed him with over and above someone else. And this is jealousy and envy.
Just as what has been confirmed by Shaykhul Islam Ibn Taymiyyah (Rahimahullah) said: “Jealousy and Envy is disliking a person for that which Allah has blessed him with over and above others”
