The following verses of the holy Qur'an beautifully describe these facts: "And certainly We gave Moses the Book (Torah) and after him We sent (many) apostles one after another, and We gave Jesus, son of Mary, clear proofs (of Allah's sovereignty) and we strengthened him with the holy spirit (angel Gabriel). What! whenever then an apostle came to you with that (teachings) which your souls did not desire, you were insolent, so you called some (apostles) liars and some (apostles) you slew.

And they (Jews) say: Our hearts are covered. Nay, Allah has cursed them on account of their unbelief; so little it is that they believe.

And when there came to them a Book (Qur'an) from Allah, verifying that which they have (Torah), although before that they used to pray for victory over those who disbelieved, but when there came to them that (Prophet) which they did recognize, (to be the truth) they disbelieved in him; so Allah's curse is on the unbelievers." Sura Baqara (2:87-89) The events which were foretold to the Jews in their books and which they were awaiting as manifest signs of the great Reformer's appearance did take place before the coming of Muhammad (s.a.w.), a fact towards which the Qur'an points: "...

although before that they used to pray for victory over those who disbelieved, but when there came to them that (Prophet) which they did recognize (to be the truth) they disbelieved in him ...".

Sura Baqara (2:89) Commenting on the revelation of the above verse, the Prophet's cousin, Abdullah Ibn Abbas who was a renowned exegete says: The Jews used to invoke Allah, in the name of the awaited Prophet (before declaration of Muhammad's (s.a.w.) prophethood) against the Arab tribes of Aws and Khazraj .

But when Allah commanded Muhammad (s.a.w.) to publicly announce his prophethood they disbelieved in him and went back on their words; on the pretext that he was not from the Israelites but was an Arab and thus they shamelessly denied what they used to say in his praise.
