Those (who embraced Islam from Bani Israel) to whom We gave the Book [the Taurat (Torah)] [or those (Muhammad's Peace be upon him companions) to whom We have given the Book (the Quran)] recite it (i.e. obey its orders and follow its teachings) as it should be recited (i.e. followed), they are the ones that believe therein. And whoso disbelieves in it (the Quran), those are they who are the losers. (Tafsir Al-Qurtubi. Vol. 2, Page 95).
