The vowel on the 'ya' changes from a damma to a fatha, shifting the verb from Form IV (to lead others astray) to Form I (to stray oneself).

Hafs reads the verb with a fatha (subjunctive/mansub), coordinating it with 'to lead astray' (li-yudilla). The variant reads it with a damma (indicative/marfu'), coordinating it with the earlier verb 'who buys' (yashtarī).

In Hafs, 'mithqāla' is read in the accusative case (mansub) as the predicate (khabar) of the verb 'taku' (meaning 'if it [the deed] be the weight'). In the variant, 'mithqālu' is read in the nominative case (marfu') as the subject (ism) of 'taku' (meaning 'if the weight be').

The variant reads the word as a singular noun ('blessing', adding the letter taa) instead of the plural form ('blessings') found in Hafs.

The noun changes from nominative (as the subject of a new clause) to accusative (coordinated with the preceding accusative subject).

The verbal prefix changes from a ya' (two dots below) to a ta' (two dots above), shifting the subject from third person plural ('they call') to second person plural ('you call').

Hafs uses the Form II verb 'yunazzilu' (with a shaddah and fatha), which implies a gradual, continuous, or repeated sending down of rain. The variant uses the Form IV verb 'yunzilu' (with a sukun), which refers to the general act of sending down.
