Because it is a far more plausible account of how Baha'u'llah came by some (at least) of his religious knowledge.
Why it is more plausible? How do we know it is more plausible?
Why would she lie about that in a letter to her nephew?
I didn't say she nessesarily lied. Even if she did not, I already showed you, why in my view, what she says does not disprove the claim of Bahaullah that His knowledge is not through human learning.
I pointed out that, since she had joined with Yahya Azal, who was enemy of Bahaullah, she can very possibly be biased, and thus exegerated or presented the facts inaccurately to refute Bahaullah. Thus, we cannot just take her words for it. We need to analyze it, and consider it in the light of other evidences.
Baha'u'llah had 16 siblings - should we ask all of them? OK - we know that at least two died before Baha'u'llah became prominent, at least 5 expressly did not believe in him, and 3 certainly did - at least for a time - possibly 4 but I'm not exactly sure about the Russian ambassador's official's wife (one of his sisters) - maybe she was, or maybe she just took pity on her brother and gave him a home for a while. The rest we don't know. So his siblings were definitely split on the issue, and as far as we can possibly tell, slightly in favour of disbelief.So why would you take the word of the smaller number of his siblings rather than the larger number who disbelieved?
No other sibling of Bahaullah said that Bahaullah had studied, or learned His knowledge from others. They did not become believers, perhaps because they did not give it a thought that, the innate knowledge of Bahaullah is a proof of His divinity.
But, since Kalim, was truly a believer in Bahaullah and had accepted to suffer in prison because of His belief in Bahaullah, we can conclude that in His view, Bahaullah was not lying. Otherwise why would Kalim be willing to go through imprisonment for a lying imposter brother? So, is even with Abdulbaha. Why would He be willing to go through so many years of imprisnment if He did not truly believe in Bahaullah?
No let's not - we've already done that - it is clear that she meant to indicate that Baha'u'llah had gained a clear understanding of "Mahdi"-related prophecies long before he decided to take on the mantle of a "Manifestation" for himself.
Yes, she meant to indicate that Bahaullah had learned these things from others. But you seem to just take her words for it. The problem that i see is, Bahaullah had clearly a different view on Mahdi, than the scholars of His time. So, i am not sure why you think He learned from them.
Yes - a book that contains oblique, incomplete and skewed views of other religions.
This is yet what you need to prove.
Yes - a book that has a slanted and somewhat shallow understanding of religions that were not studied in depth.
Not sure what you mean here. Is Iqan in your view has a shallow understanding of religions?!
Many of the Muslim scholars or even Christians have believed in Bahaullah by reading this Book!
We have already shown by this thread that this is not the case. I gave an example that is not there - apart from the very poor example you gave in the OP you have yet to present any positive evidence that the Iqan actually contains any genuine consistency with any substantive scriptural doctrine from any tradition other than the Qur'an - and even that is questionable.
But you stopped and did not reply to my last reply to yours.
But really, the Iqan is more accurately described as a commentary on the Qur'an. It certainly does not contain "all scriptures" in condensed form - as you have utterly failed to demonstrate.
If you think it does not contain all scriptures in condensed form, you need to prove this by trying and trying until you find one. I think you expect the scriptures of other religions to be literally copied in Iqan to be considered containing having all scriptures, whereas, many of the things in the past scriptures are symbolic, and should not be taken literally, thus, their correct explanations are in Iqan, not literally same stories. Now, even name of Krishna or Buddha are not in Iqan either, but the essence of their teachings is, in a condensed form. If you say, not, you need to show which one!
