﴿ ۞ لَيْسُوا۟ سَوَآءًۭ ۗ مِّنْ أَهْلِ ٱلْكِتَٰبِ أُمَّةٌۭ قَآئِمَةٌۭ يَتْلُونَ ءَايَٰتِ ٱللَّهِ ءَانَآءَ ٱلَّيْلِ وَهُمْ يَسْجُدُونَ ﴾

“[But] they are not all alike: among the followers of earlier revelation there are upright people, who recite God's messages throughout the night, and prostrate themselves [before Him].”

Yet they are not all alike; some of the People of the Scripture are a community upright, that is, [upright] upon [the path of] God. He then describes them with [reference to] the states of those of uprightness. In other words, there are among them affirmers of Oneness and people of uprightness.
