Just on the name "Allah", I found this, which I knew but couldn't explain properly. Its worded perfectly for you to see. Its a lot more understandable and applicable if you speak Arabic:
The use of the word "Allah"
Should Christians Use Allah in Bible Translation?
by Joshua Massey
The question of translating God as Allah is hotly debated in non-Arab lands, where many sincere Christians are convinced Allah is a false god. Ironically, this debate doesn’t exist for Arab Christians, who have continually translated elohim and theos (the primary terms for God in Biblical Hebrew and Greek) as Allah from the earliest known Arabic Bible translations in the eighth century till today. Most scholars agree that Allah is the Arabic cognate of the Biblical Aramaic elah and Hebrew eloah, which is the singular of elohim, a generic word for God used throughout the Old Testament. In fact, it is nearly impossible for linguists to determine which of these three terms appeared first in the Ancient Near East, or if they all derived from a hypothesized proto-Semitic language. Though precise origins are uncertain, ancient usage is not. As in English, the Bible uses elah and elohim for both the Most High God and false gods—English uses an upper or lower case “g” to distinguish between these two. By contrast, Muslims never use Allah to refer to a false god, but only the One True God, the God of Abraham, Isaac and Jacob.
Isayah 65:15, "
And the names of your gods will remain as a trap to My chosen; for Yahweh our Father will slay you, but he will give His servants a Name; Yahweh, that will remain forever."
The oldest version of the "OT" called the "J" writings uses YHWH not Elohim or Adonai, the next version uses Elohim , the "E" writings. this was forged in by the Masorites when they added vowel points to the Hebrew alphabet.
Yeremyah 23:26-27, "How long will this be in the heart of the prophets who prophesy lies? Yes, they are prophets of the deceit of their own minds; Who devise; plan and scheme, to cause My people to forget My Name through their dreams, which they tell every man to his neighbor, just as their fathers have forgotten My Name for Baal; (
Lord)."
It is believed by some scholars, and others disagree, that in origins of hebrew yl was used not EL, yl denoted strength and power. yl shaddai, not a name but = strength almighty.
El was the head of the Cannanite pantheon, it only got incorperated when some hebrews worshipped the gods of Cannan.
2 Kings 17:33-34, "They were taught how they might worship Yahweh,
but instead they worshiped their own gods according to the customs of the nations from which they had been brought. To this day, they continue to practice their former pagan customs. They do not reverence Yahweh, nor do they follow the statutes, ordinances, Laws, and commandments which Yahweh had commanded the children of Yaaqob, whom He named Isray.
