March 7. On this date in 1938, a letter was addressed to an individual believer on behalf of Shoghi Effendi stating that "the reference to Ishmael is correct, although it disagrees with the text of the Bible. The Qur'án too corroborates this statement of Bahá'u'lláh, and as this book is more authentic than the Bible, it is obvious that it should be given precedence over the Jewish and Christian Holy Scriptures, which cannot be considered as being wholly authentic."

This statement is corroborated by other letters by Shoghi Effendi and the Universal House of Justice.

For example...

The Bahá'ís believe what is in the Bible to be true in substance. This does not mean that every word recorded in that Book is to be taken literally and treated as the authentic saying of a Prophet. A striking example is given in the account of the sacrifice which Abraham was called upon to make. The Guardian of the Faith confirms that the record in the Qur'an and the Writings of Bahá'u'lláh, namely that it was Ishmael, and not Isaac as stated in the Old Testament, whom Abraham was to sacrifice, is to be upheld. In one of His Tablets 'Abdu'l-Bahá refers to this discrepancy, and explains that, from a spiritual point of view, it is irrelevant which son was involved. The essential part of the story is that Abraham was willing to obey God's command to sacrifice His son. Thus, although the account in the Torah is inaccurate in detail, it is true in substance....
...The Bahá'ís believe that God's Revelation is under His care and protection and that the essence, or essential elements, of what His Manifestations intended to convey has been recorded and preserved in Their Holy Books. However, as the sayings of the ancient Prophets were written down some time later, we cannot categorically state, as we do in the case of the Writings of Bahá'u'lláh, that the words and phrases attributed to Them are Their exact words (9 August 1984 to an individual believer)
