ٱلَّذِينَ ءَاتَيْنَـٰهُمُ ٱلْكِتَـٰبَ يَتْلُونَهُۥ حَقَّ تِلَاوَتِهِۦٓ أُو۟لَـٰٓئِكَ يُؤْمِنُونَ بِهِۦ ۗ وَمَن يَكْفُرْ بِهِۦ فَأُو۟لَـٰٓئِكَ هُمُ ٱلْخَـٰسِرُونَ

Those to whom We have given the Scripture, who follow it as it deserves, are the ones who truly believe in it. Those who deny its truth will be 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).
