Dear Brother Naushad, SA
Please read the following link which I am providing here.
This is the best explanation for your questions concerning 4:101-103 and so far I have yet to see this understanding/explanation refuted. In fact, as far as I know there haven't been any attempts by anyone to do so. Please also keep in mind that this is NOT my research, but an explanation and understanding which I find myself in TOTAL agreement with.
