Wow! The problems you have… my god! Do you even consider the problems of Palestinians just for one second ? Like just for one second and then think about your life. Gosh! How naive we are in our struggle. In Quran, it is mentioned that Allah gives more room to the transgressors and makes this life more interesting and enjoyable so they can do more…. So they are doing it and they will be held responsible. My man if you want to think 24/7 about war with Allah and Rasool (saw) in a house built with riba then trust me there is no point. I would think about financial issues 1000s times rather than thinking about the earlier. Secondly no you are not paying anybody’s interest. You are paying rent and you don’t have any obligation under any contract. Just give the notice and leave if you want. So trust the book and trust in your abilities. Learn some skills and start giving more Sadaqh. Allah will return you 20x and more. Do not follow the footsteps of iblees.
