ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ طُوبَىٰ لَهُمْ وَحُسْنُ مَـَٔابٍ
Allazeena aamanoo w a'amilus saalihaati toobaa lahum wa husnu ma aab
Those who believe and do righteous deeds — blessedness is theirs, and a beautiful return.
Ṭūbā lahum reads as an exclamation of good over someone, the shape Arabic uses to wish another person well, and commentators split over what the word itself is. Some take it as a verbal noun of goodness, so that the line pronounces gladness on them; others treat it as a proper name, of a tree in the garden described in several narrations. The sentence carries no verb at all, which lets the wish stand as a statement.
