لَا رَيْبَ فِيهِ
There is no doubt in it.
This places «fīhi» after the negative expression, so the denial of doubt is connected to its object. It contrasts with «lā fīhā ghawl», where the locative precedes the negated noun and can carry a contextual restrictive force.
It is unsafe to translate every early prepositional phrase as “only here.” One must first identify the predicate, the scope of negation, and the contextual contrast being made.
