Small particles can determine the structure of an entire legal ruling. Wa may indicate conjunction without sequence, fa close succession, and thumma order with an interval. Their effects cannot be swapped without evidence.
Bal introduces replacement or correction, lakin qualification or contrast, and aw alternatives. In divorce, acknowledgement or contracts, a later particle does not necessarily undo a legal effect already established by the earlier words.
Hatta and ila raise endpoint questions; 'ala may indicate obligation, fi containment, and ba attachment and related meanings.
A sound interpretation combines the particle's linguistic force, its particular sentence and the time at which legal consequences arise.
