Staking in crypto is like interest in Fiat.
You lend (stake) your crypto and get reward (interest) for it.
I suggest all my Muslim brother to stay away from this new kind usury.
What is Muslims?
Muslims are a group of people who adhere to a certain religion and in this case it is aimed at Islam, so these Muslims are not suitable to join the staking program because it is considered usury, and usury in Islamic law is haram, so the OP prohibits Muslims from joining the staking program does not approach staking because it is usury in Islamic law.
Nice explanation, and I truly agree with that, if you are a real muslim, you should abide the law and live with peace. However, I do believe that there are muslims who are violating this, so hopefully they'll realize that the law is very important and it should be followed.
I'm not a muslim and this is not against in our teaching, but I will respect my muslim brothers here.
