The context of the verse makes it clear that it is not attempting to enumerate in detail all the articles of faith in which one should believe, or all the principles of conduct which one should follow in order to merit reward from God. These matters are mentioned elsewhere, in their appropriate places. The aim of the verse is merely to repudiate the illusion cherished by the Jews that, by virtue of their being Jews, they have a monopoly of salvation. They had long entertained the notion that a special and exclusive relationship existed between them and God. They thought, therefore, that all who belonged to their group were predestined to salvation regardless of their beliefs and actions,. whereas all non-Jews were predestined to serve as fodder for hell-fire.

To clarify this misgiving the Jews are told that what really matters in the sight of God is true faith and good deeds rather than formal affiliation with a certain religious community. Whoever has true faith and good deeds to his credit is bound to receive his reward, since God will judge people on the basis of merit rather than on the grounds that a man's name happens to be listed in the world as a member of one religious community or the other.

All we can say is that while the Children of Israel were making their covenant in the shadow of Mount Sinai, they witnessed an awesome phenomenon and felt as if the mountain was about to fall upon them. (Verse 171 of Surah al-A'raf) seems to portray this. See also (n. 132 in that surah.)
