It's absolute NONSENSE to claim that 'allah' is YHWH in the Bible. 'Allah ' is just a generic title, like 'God' in English, 'Dios' in Spanish. 'Theos' in Greek, etc. Using this generic title in Arabic translations of the Bible doesn't mean that the God of the Bible and 'allah' of the Quran are one and same. What determines which 'God/ Allah' is being spoken of is context and content...in context of the Bible, there's a very different CONCEPT...they are irreconcilably different. The major distinctions being that God in the Bible is Father, His very nature and being is described as the Trinity, one God, 3 distinct yet indivisible divine Persons, not 3 'gods' as the human authors of the Quran absurdly claimed...He has a Son...NOT a literal biological son, the byproduct of procreation...another perverted distortion found in the Quran. No...absolutely NO...'allah ' isn't found in Bible. That's a blatant lie, made up to try to reconcile another false claim...that 'allah' sent the Taurat and the 'Injeel'. That's another major error in the Quran since the Taurat is only the first 5 books of Old Testament , or Tanakh...commonly referred to as The Law, Psalms and the Prophets. The Arabic pagan deity, 'allah ' originated throughout Arabia during the pre-islamic period, before Muhammad ever lived. It was Supreme deity in the numerous Arabic pagan pantheons located throghout Arabia, as described by Diadorus Siculus, a Greek historian, writing before Islam existed. The one in Mecca came into existence in roughly 500 AD, built by Yemeni pagans about 100 years after Mecca came into existence in 400 AD...2,200 years AFTER ABRAHAM DIED. meaning that he wasn't a Muslim, because Islam nor its Arabic pagan pantheon existed in his lifetime. In fact, your religion wasn't originally called Al Islam!
"The religion with Allah is al-Hanifiyyah (the Upright Way) rather than that of the Jews or the Christians, and those who do good will not go unrewarded. (as-Suyuti, Al-Itqan fii Ulum al-Qur'an, p.525).
According to at-Tirmithi in his Kitab al-Tafsir, one of the sections of his Jami', his collection of hadith records which rates as one of the six major works of authentic tradition literature in Islam alongside the Sahihs of al-Bukhari and Muslim and the three sunan works of Abu Dawud, an-Nasai and Ibn Maja, this verse at one time formed part of Suratul-Bayyinah (Surah 98) in the Qur'an (Nöldeke, Geschichte, 1.242). This is quite possible as it fits well into the context of the short surah which contains, in other verses, some of the words appearing in the missing text, such as diin (religion, v.5), 'aml (to do, v.7), and hunafa (upright, v.4), and also contrasts the way of Allah with the beliefs of the Jews and the Christians.
It is also significant to note here that, whereas the standard text of Surah 3.19 today reads innadiina 'indallaahil-Islaam - "the religion before Allah is al-Islam (i.e. the Submission)", Ibn Mas'ud read in place of al-Islam the title al-Hanifiyyah, i.e. "the Upright Way" (Jeffery, Materials, p.32), thus coinciding with the text said to have been part of Surah 98 by at-Tirmithi. At the beginning of Muhammad's mission there were a number of people in Arabia who disclaimed the worship of idols and called themselves hunafa, specifically meaning those who follow the upright way and who scorn the false creeds surrounding them.
It may well be that Muhammad first chose this same title al-Hanfiyyah to describe his own faith but, as his religion took on its own unique identity, he substituted al-Islam for it and called believers Muslims, signifying that they were not only followers of the right way but, at the same time, submitters to Allah who reveals that way and commands obedience to it. This would account for the lapse of the earlier title in the Qur'an and the omission of the verse we have been considering from its text."
The claim that 'allah ' is in the Bible is absolutely false.
