Khaulah bint `Thamir (May Allah be pleased with her) reported: Messenger of Allah (ﷺ ) said, “Many people misappropriate (acquire wrongfully) Allah’s Property (meaning Muslims’ property). These people will be cast in Hell on to the Day of Resurrection”.
Sahih Bukhari
This is general i.e. we’re not talking about ONE person who is in-charge of taking care of the wealth of the ummah. The Prophet ﷺ is not talking about leaders alone, he’s talking about anybody who has to take care of wealth but didn’t put it in the proper place.
Wealth in general belongs to Allah. So, if the money is in your pocket, it means you’re a caretaker or somebody who’s monitoring it and meant to put it in the right place.
If you have money, you have to realise there’s two questions related to it:
1. How did you get it?
2. How are you spending it?
For example, a man is getting married and he wants to prove he’s rich. He gets so much food, the remaining of which ends up getting thrown…he’ll be questioned about it. So what do you think of one who’s wasting wealth?
Abu Huraira (may Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, “The poor Muslims will enter Paradise before the rich by half of a day, the length of which is five hundred years.” (Sunan al-Tirmidhī)
What’s this half a day? 500 years! Why are the rich ones left behind? It doesn’t mean the rich ones will go to hell. Wealth can take you to a position higher than the fuqara if you utilise it properly. On the Day of Judgement, Allah will ask you about every single ringgit; how did you get and how did you spend it.
