The imperfect verb prefix changes from nun (one dot above) to ya (two dots below), shifting the subject from the majestic 'We' to the third-person 'He'.

The initial letter changes from 'Ta' (tūʿadūna) to 'Ya' (yūʿadūna) by shifting the placement of the dots, changing the verb from the second person 'you' to the third person 'they'.

Changing the vowel on the initial hamza from a fatha in Hafs to a kasra in the variant shifts the grammatical form from the plural noun 'adbār' (ends/backs) to the verbal noun 'idbār' (retreating/departing).

Hafs reads with a lightened 'shin' (tashaqqaqu), whereas the variant reads with a shadda on the 'shin' (tashshaqqaqu), representing the assimilation of an original second 'ta' (tatashaqqaqu). This morphological intensification shifts the meaning from a standard splitting to a more severe and vigorous rupturing.
