I thought questions were already answered by Br. Jawaid Ahmad. But let’s revisit them.
Q. Is to work in bank, investing, and taking interest of bank accounts in our today societies OK?
A. This is closed-ended question, and so the answers would be 1. Yes, 2. No and 3. Don’t know! Aside from theological stand point, some answers would reflect massive capitalist compulsion that today engulfs every walk of life in some or other way. Instead an open-ended question be appropriate if you like to open up inquiry into the nature, problems and solutions to investment and banking of current time.
Q. What about those who will live in a non-Quranic country when there is a true Quranic State somewhere?
A. The question is presumptive and with no ground for accurate answer, except some opinion. Should wait until somewhere Quranic state is established, and if they allow migration from all sides to determine its fate.
Q. These two questions are my main queries in my mind, and surely your help will solve one my biggest problems.
A. Doctor, not even quacks can figure out judgement unless problems are explained.
