Surah 4. An-Nisaa', Ayah 162

I.e., those from among the Jews who do not content themselves with a mere observance of rituals, but try to penetrate to the deepest meaning of faith.

According to the grammarians of the Basrah school, and especially Sibawayh, the use of the accusative (mansub) case in the expression al-muqimin as-salah ("those who are constant in prayer") - instead of the nominative al-muqimun - is a legitimate grammatical device meant to stress the special, praiseworthy quality attaching to prayer and to those who are devoted to it (see Zamakhshari and Razi); hence my interpolation of "especially" between brackets.
