Quote:
{10:28} And [mention, O Muhammad], the Day We will gather them all together - then We will say to those who associated others with God, "[Remain in] your place, you and your 'partners.' " Then We will separate them, and their "partners" will say, "You did not used to worship us,
I suspect that "did not used" is incorrect grammar. I think the same meaning can be conveyed with a present perfect continuous tense, e.g.,
{10:28} And on the Day We will gather them all together - then We will say to those who associated [others with God in worship], "[Remain in] your place, you and your 'partners.' " Then We will separate them, and their "partners" will say, "You have not been worshiping us,"Quote:
{10:30} There, [on that Day], every soul will be put to trial for what it did previously, and they will be returned to God, their master, the Truth, and lost from them is whatever they used to invent.
I suggest,
{10:30} There, [on that Day], every soul will experience what it did previously, and they will be returned to God, their true Master, and will be lost from them whatever they used to contrive.
