Gabriel is the name of one of the Archangels, considered by many to be one of the most senior angels. In Muslim belief, one of his main responsibilities was to take divine revelation from God (or Allah in Arabic) and deliver it to his prophets and messengers, like Jesus, Moses and Muhammad -- the unifying aspects of these revelation being that God is One. In Arabic, his name is written Jibreel. There are different beliefs about Gabriel held by Jews and Christians.
