زَعَمَ قَائِلٌ: تَأَخَّرَتِ الْقَافِلَةُ فَضَلَّتْ، وَتَوَقَّفَ الدَّلِيلُ فَجَبُنَ.
Someone claimed: The caravan was late, so it got lost; the guide stopped, so he was cowardly.
Here fāʾ frames two unsupported inferences as conclusions. A sound revision separates the observable events from disputed interpretations:
تَأَخَّرَتِ الْقَافِلَةُ، وَلَمْ يَثْبُتْ أَنَّهَا ضَلَّتْ؛ وَتَوَقَّفَ الدَّلِيلُ احْتِيَاطًا.
The caravan was delayed, but it has not been established that it was lost; the guide stopped as a precaution.
The linking particle, evidential force, and qualifying phrase now work together to preserve the intended distinction.
