According to several authentic Traditions, some of the learned men from among the Jews of Medina described Gabriel as "the enemy of the Jews", and this for three reasons: firstly, all the prophecies of the misfortune which was to befall the Jews in the course of their early history were said to have been transmitted to them by Gabriel, who thus became in their eyes a "harbinger of evil" (in contrast to the angel Michael, whom they regarded as a bearer of happy predictions and, therefore, as their "friend"); secondly, because the Qur'an states repeatedly that it was Gabriel who conveyed its message to Muhammad, whereas the Jews were of the opinion that only a descendant of Israel could legitimately claim divine revelation; and, thirdly, because the Qur'an - revealed through Gabriel - abounds in criticism of certain Jewish beliefs and attitudes and describes them as opposed to the genuine message of Moses. (For details of these Traditions, see Tabari, Zamakhshari, Baghawi, Razi, Baydawi, Ibn Kathir.) As regards my rendering of ma bayna yadayhi in verse {97} as "whatever there still remains of earlier revelations", see surah {3}, note [3].
