Generality and specification are essential in translation. If the original addresses an entire relevant class, the translation should not narrow it without evidence; if a ruling is conditioned on a particular situation, the translation must not turn it into an unrestricted statement.
For example, kull (“all/every”) and baʿḍ (“some”) differ materially. An exception or condition attached to a ruling must also survive translation. A smooth but careless version can otherwise change a legal or theological implication.
Practical test: Who is addressed? How broad is the statement? Is there a condition, limitation, or exception in the Arabic?
