" " This is because Allah has sent down the Book with the Truth; and surely those who differ in the Book are in flagrant schism." Commentary: Before the advent of the holy Prophet of Islam (p.b.u.h.) , the Jewish scholars used to tell their people about that happy advent and described the signs of that promised Prophet for them from the Torah.
But as soon as the Prophet of Islam (p.b.u.h.) was divinely appointed and announced his Call, they did not confess the prophethood of Muhammad (p.b.u.h.) for they thought they would lose their position, wealth, etc. It was why they neglected every thing and concealed the 58 Truth. Such people, by concealing the fact, might remain in their position receiving some presents and gifts for a length of time but this is a little price comparing to that great sin of theirs.
" Surely those who conceal any part of the Book which Allah has sent down (to them) , and sell it for a small price- ..." What they take and eat in this bargain is naught, indeed, but Fire. This meaning is similar to the content of the verse where eating the wealth of orphans is likened to Fire, too, as if they ate Fire in their bellies.
(1) So, it says: "...they shall eat naught but Fire into their bellies, ..." On the Day of Resurrection, Allah will not speak to these people mercifully, while the believers can speak with Him then.
