Christians should not bother with Britannica or Wikipedia to determine the true nature of Allah and Islam. Go straight to the Koran (Qu'ran) and learn from the primary source.
Allah attacks Jesus the son of Mary thus: Sura 9: 31. They have taken their rabbis and their priests as lords instead of Allah, as well as the Messiah son of Mary. Although they were commanded to worship none but The One God. There is no god except He. Glory be to Him; High above what they associate with Him.
Allah says Islam must prevail over all religions: Sura 9:33. It is He [Allah] who sent His Messenger [Muhammad] with the guidance and the religion of truth, in order to make it prevail over all religions, even though the idolaters dislike it. [Note: According to the Koran Christians are idolaters because Jesus is not God and must not be an "associate" of God]
