Envy Of Wealth
There’s no problem in wanting to be rich and working hard towards your goal. Just make sure that you remain conscious of God at all times and discipline your actions and decisions to always remain within the bounds set by Him. That’s exactly what taqwa is.

What’s forbidden is being jealous of them, hating them for their money, and wanting to have all of their money yourself.
