Yes, I understand how Baha'is think of it. But I myself reject the concept of 'scriptures' and so have no interest in studying them.
Anyway, I just find it a bit odd the way Baha'is assume that the only 'scriptures' are the ones embraced by Baha'is. As if all the world agrees on true scriptures vs. false scriptures.
Since you reject the "concept of scriptures" that's your business... but for Baha'is we generally regard the scriptures of previous dispensations as follows..
The Buddhist and Hindu scriptures ... in a letter dated November 25, 1950 written on behalf of Shoghi Effendi to an individual believer, there is this statement: 'We cannot be sure of the authenticity of the scriptures of Buddha and Krishna...'.
Baha'is accept the Torah and the Gospels of the Bible:
"...the Torah that God hath confirmed consists of the exact words that streamed forth at the bidding of God from the tongue of Him Who conversed with Him (Moses)."
(From a recently translated Tablet of Bahá'u'lláh)
"Know ye that the Torah is that which was revealed in the Tablets to Moses, may peace be upon Him, or that to which He was bidden. But the stories are historical narratives and were written after Moses, may peace be upon Him."
(From a recently translated Tablet of 'Abdu'l-Bahá)
"That City is none other than the Word of God revealed in every age and dispensation. In the days of Moses it was the Pentateuch; in the days of Jesus, the Gospel; in the days of Muhammad, the Messenger of God, the Qur'án; in this day, the Bayan; and in the Dispensation of Him Whom God will make manifest, His own Book -- the Book unto which all the Books of former Dispensations must needs be referred, the Book that standeth amongst them all transcendent and supreme."
(Baha'u'llah, Gleanings from the Writings of Baha'u'llah, p. 269)
