“Yashrabu bihā ʿibādu Allāh”
“God’s servants will drink from it.” (al-Insān 76:6, excerpt)
Here “bihā” can be elucidated through “minhā,” drinking from the source. The governing verb and the spring under discussion establish the relation.
“Fa-sʾal bihi khabīrā”
“Ask someone knowledgeable about Him/it.” (al-Furqān 25:59, excerpt)
In this construction, “bihi” is understood through the relation “ʿanhu,” concerning the one in question. The same preposition occurs in both examples, but the verbs yield different contextual relations.
This is why the interpreter should not assign a single mechanically substituted meaning to every occurrence of the particle bāʾ.
