Allah is Hubal, which is Ba'al. Muhammad reinstated the chief deity of his tribe. Muslims still have the the little stars next to the crescent moon; the daughters of Hubal: Al-'uzza, Allat and Manat. In keeping with the occultic belief of masculine and feminine aspects of the moon, Catholicism is the composite of Islam, with Marie/Ishtar/Isis/Semiramis as the moon goddess. There is the Bible, and then there are all derivatives of Bablyonian witchcraft. All of these offshoots from the latter are finding their way home as we speak. As Albert Pike called it, "the pure doctrine of Lucifer". Lucifer being the deliberate and deceptive mistranslation of Heylel, "the one who rages".
Exodus 20:2-3 - Anokhi YHWH Eloheikha asher hotze'tiyekha me'eretz mitz'rayim mibeit 'avadim, lo yih'yeh-l'kha akherim al-pani'ya.
Literally: I Yahweh G-d who brought you out of Egypt a slave, no other god are you to belong.
Al-Baqara 2:163 - Wa ilaahukum illaahunw waahid, laaa ilaaha illaa Huwar Rahmaanur Raheem
Literally: And your god is god only, there is no god except him the most gracious, the most merciful. (no name given, why does Allah not like to identify himself?)
Who is Allah? Allah is not a name, but a title. It is a generic name for "the God", just as the word "El" is the generic name for god in Mesopotamia. Through the moon we can connect Lord Shiva as well as many other pagan religions to one source. Therefore, there are essentially two sides two this: The Biblical position and the pagan position. Atheism has its origins in luciferianism (the man evolving to become the "god man"). Many of these pagan religions acknowledge that there is a creator G-d whow as supposedly killed, doesn't actively involve himself with creation or who lost a battle against other gods and was replaced.
Your first mistake was to connect three religions with one paraphrase that supposedly connects the three. Your actual first mistake was errantly believing that there were three religions. The Tanakh is the Bible. The Tanakh is an acronym for Torah (Books of Moses), Nevi'im (Prophets; 19 books of the 'Old Testament'), and Ketuvim. You cannot separate the Bible and the Tanakh, as they are the same thing. You spelled Q'uran incorrectly as well.
