119. " here you are, loving them while they do not love you!
though you believe in all books
and when they meet you, they say: ` we believe ',
but when they are alone, they bite the ends of their fingers in rage against you.
say: ` die in your rage!'. surely allah is aware of what is in the breasts."

commentary:
in this verse it addresses the muslims and says that you love them
because of relationship or neighbourliness, or for other reasons, neglecting
the fact that they do not like you. it is in the case that you believe in all
the books that have been sent down by allah (irrespetive of your own
book and the heavenly book of theirs), but they do not believe in the
revealed book you have.

" here you are, loving them while they do not love you!
though you believe in all books; ..."

then, the qur'an introduces the real feature of this group of the
people of the book, who are hypocrites, when it says:

"... and when they meet you, they say: ` we believe ',
but when they are alone, they bite the ends of their fingers in rage
against you. ..."

it says to the prophet to tell them that they would die with the rage
that they have and this grief will be with them until the day of their death.

"... say: ` die in your rage!'. ..."

you were not aware of their condition, but allah is, because:

"... surely allah is aware of what is in the breasts."
