وَمَن تَابَ وَعَمِلَ صَـٰلِحًا فَإِنَّهُۥ يَتُوبُ إِلَى ٱللَّهِ مَتَابًا
Wa man taaba wa 'amila saalihan fa innnahoo yatoobu ilal laahi mataabaa
Kim tevbe edip yararlı iş işlerse, şüphesiz o, Allah'a gereği gibi yönelmiş olur.
Whoever repents and does good — truly turns to God in sincere repentance.
The promise just before this is an unusual one, that God exchanges a person's bad deeds for good, and this line sets its terms by counting repentance together with what someone then does. The Arabic doubles the root t-w-b and lands on mataban, a turning-place, which gives repentance a location, somewhere a person arrives at. Commentators differ over whether that exchange reaches deeds already committed or only what comes after.
