Those We have given the Book follow it as it should be followed. It is they who ˹truly˺ believe in it. As for those who reject it, it is they who are the losers.

Those (who embraced Islâm from Banî Israel) to whom We gave the Book [the Taurât (Torah)] [or those (Muhammad’s صلى الله عليه وسلم companions) to whom We have given the Book (the Qur’ân)] recite it (i.e. obey its orders and follow its teachings) as it should be recited (i.e. followed), they are the ones who believe therein. And whoso disbelieve in it (the Qur’ân), those are they who are the losers. (Tafsir Al-Qurtubî).
