We're a group of students, studying at a prestigious University, we had to shift from city campus to its permanent campus due to some new Govt. policies. Currently we're living in a rural area and have been facing various problems, but the main issue abou which I am going to request you to clarify me is that, over here two students have made such an accommodation crisis that if you need a room for living you have to take the room from them with double and sometimes tripled rent price than if you were able to take it directly from the owner of the building. For example, a room would cost 1500 bucks per month if you take it from the owner, but now you have to spend 4000 bucks (more or less) for that room monthly only because of those two students, as they have already taken those room and left us with no choice but to take rooms with that high price from them. And due to lack of adequate apartments, we have no alternatives to stay in other places or buildings as they have taken all of them and making a lot of money out of it. And we are the victims of their business.
Now my question is, what they are doing, according to the rulings of islam, is it halal or haram business?
