The weight may be manifested through records of deeds or other forms that Allah makes weighable. Revelation affirms records of actions, and the processes of the Hereafter need not operate in every detail as worldly mechanisms do.
Established conclusion: weighing is real, and the value of good and evil will be displayed.
Unspecified modality: whether deeds themselves, records, or another divinely created form are weighed must not be asserted with certainty where revelation has not definitively specified it.
This affirms the text without imposing an unsupported physical model.
