Baha'u'llah would copy exact phrases from the writings of others and claim they were divine revelations.

In his Tablet of Wisdom Baha'u'llah claims the Tablet is a Divine revelation:

"This is an Epistle which the All-Merciful hath sent down from the Kingdom of Utterance." (Baha’u’llah, Tablets of Baha’u’llah Revealed After the Kitab-i-Aqdas, p. 137)

He then writes these historically incorrect statements in the Tablet:

"Empedocles, who distinguished himself in philosophy, was a contemporary of David, while Pythagoras lived in the days of Solomon, son of David, and acquired Wisdom from the treasury of prophethood. It is he who claimed to have heard the whispering sound of the heavens and to have attained the station of the angels. In truth thy Lord will clearly set forth all things, if He pleaseth. Verily, He is the Wise, the All-Pervading." (Baha’u’llah, Tablets of Baha’u’llah Revealed After the Kitab-i-Aqdas, p. 145)

These are verbatim statements from the books of Historians. This was so bad for Baha'is that they were forced to justify it by claiming in a footnote that:

"In many of the passages that follow concerning the Greek philosophers, Baha’u’llah quotes verbatim from the works of such Muslim historians as Abu’l-Fath-i-Shahristani (1076–1153 A.D.) and Imadu’d-Din Abu’l-Fidá (1273–1331 A.D.)." (Baha’u’llah, Tablets of Baha’u’llah Revealed After the Kitab-i-Aqdas, p. 145, footnote)

Apparently in Baha'ism God sends down wrong historical facts that he has copied verbatim from Sunni Muslim history books:

"This is an Epistle which the All-Merciful hath sent down from the Kingdom of Utterance." (Baha’u’llah, Tablets of Baha’u’llah Revealed After the Kitab-i-Aqdas, p. 137)
