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).
Those to whom We have given the Book recite it with its true recital. They [are the ones who] believe in it. And whoever disbelieves in it - it is they who are the losers.
(2:121) There are those, even among the people of the Scripture, who read the Book as it should be read and believe in it sincerely; *122 as for those who reject it, they are indeed the losers.
*122). This refers to the pious element among the People of the Book. Since these people read the Book with sincerity and honesty of purpose, they are inclined to accept whatever they find to be true according to it.
