In discussing ibdāl, a verb, noun, particle, or clause may be explained by a different expression that communicates its contextual sense. This does not mean replacing the Qur’an’s wording or claiming that the expressions are universally interchangeable. The exact term, an explanatory gloss, and the grammatical relation remain distinct.
A verb coupled with a particular preposition can convey a special nuance, so an interpreter may use another verb to make that nuance intelligible. The same substitute need not work in every context.
Likewise, the force of bāʾ, lām, or min depends upon the construction in which it appears. A contextual explanation of one verse cannot become an unrestricted rule for all occurrences of that particle.
