One of the major claims Bahaullah made, was that, He did not have education in religion, however, when we read His Writings which are just many, we see He had detail knowledge of Religions.
Well, then He claims, He did not acquire His knowledge through human learning, but rather He was given all knowledge to Him by God.
Let's set aside whether or not He received any knowledge from God for the purpose of this discussion.
The Question is: Is it possible to investigate this subject through available historical sources, and any other methods to come to a concrete conclusion if Bahaullah did not have any human learning in the subject of religions in particular? If possibly He had any education, how much was it, and what subject and at what level exactly?
Are there enough historical resources or anything else available to us to know if, indeed Bahaullah had not studied subjects of religions?
In His letter to the King of the Time, the ruler of Persia, Bahaullah wrote the following letter:
"I was but a man like others, asleep upon My couch, when lo,
the breezes of the All-Glorious were wafted over Me, and taught Me the knowledge of all that hath been. This thing is not from Me, but from One Who is Almighty and All-Knowing. And He bade Me lift up My voice between earth and heaven, and for this there befell Me what hath caused the tears of every man of understanding to flow.
The learning current amongst men I studied not; their schools I entered not. Ask of the city wherein I dwelt, that thou mayest be well assured that I am not of them who speak falsely."
Baha'u'llah
