1. How is the definition of a neighbour determined when no fixed authentic limit is established?
- By what people customarily regard as a neighbour. (correct answer)
- Only by the house immediately attached to yours.
- Only by people who pray in your mosque.
- By exactly forty houses in every direction in all cases.
Why
Islam strongly enjoins kind treatment of neighbours and forbids annoying them. Scholars differed about exactly who counts as a neighbour, with views including forty houses in each direction, adjacent houses, people of a locality, and other definitions. Since the reports defining neighbours as forty houses are not established as authentic according to the cited discussion, the correct approach is to refer the matter to custom: whoever people customarily regard as a neighbour is treated as such.
