Taqrīb ilā al-ṣiḥḥah uses a qualification that makes a severe exaggeration appear as near, conditional or hypothetical rather than an unqualified declaration of occurrence. This opens a space for the listener's imagination.
“He actually shone without fire” is a categorical claim. “He almost shone without being touched by fire” instead expresses nearness or expectation. The difference affects the proposition itself.
A qualifying particle can make the rhetoric more fitting without functioning as evidence that the event literally occurred.
