  Translation

121. Those (who embraced Islâm from Banî Israel) to whom We gave the Book [the Taurât (Torah)] [or those (Muhammad's Peace be upon him 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 that believe therein. And whoso disbelieves in it (the Qur'ân), those are they who are the losers. (Tafsir Al-Qurtubî. Vol. 2, Page 95).
