After looking at the videos, it's my thought (and I'm willing to be corrected) that Ergun Caner and his siblings were raised in a mixed-religion household (his father was Turkish and mother Swedish) and religion probably wasn't discussed much beyond, "What religion am I?" "Oh, you're Muslim." "Oh. Thanks, Dad!" In other words, I doubt there was much in the way of prayer and Qur'an study. I can be fairly confident in saying that, if only because of the boneheaded errors described above.
However, I found this hard to believe because I also noted that Ergun has a raft of university degrees. In fact, his website claimed that he had the following: Ergun Mehmet Caner (B.A., M.A., M.Div., Th,M., D.Min., Ph.D.) Oddly enough, though, when I went digging around, I could find no record of where these degrees were earned, so I sent him an e-mail in June asking about it, care of his website. I heard nothing back.
A few weeks later, I noticed that Ergun's YouTube debunker was back with a couple more videos and that Ergun had set up his own YouTube channel. So I posted my question as a comment on Ergun's channel (here's a screenshot since Ergun is removing comments and may remove this one in the future--click to see larger):
Ergun replied with the following in the comments on my YouTube channel (again, click to enlarge):

This is what Ergun says his degrees are:
1989 - Bachelor of Arts in Biblical Studies, Cumberland College (BA)
1992 - Master of Arts in History, Criswell College (MA)
1994 - Master of Divinity, Southeastern Baptist Theological Seminary (MDiv)
1995 - Master of Theology, Southeastern Baptist Theological Seminary (ThM)
2001 - Doctor of Theology, University of South Africa (DTh),
His dissertation is called Bellum Sacrum vs. Bellum Justum
(For those of you who don't speak Latin or are not familiar with theological terms of art, what that means is "Holy War versus Just War.")
So, in a row, that's BA, MA, MDiv, MTh, DTh.
Ok, that's fine, except for one thing. That's not what he's claiming today, Saturday, July 11, 2009. Instead, he's claiming: BA, MA, MDiv, MTh, PhD (again, click to make larger)
And this is different from what he has claimed in the recent past, as can be shown by this Google search, conducted July 11, 2009. The letters are: BA, MA, MDiv, MTh, DMin, PhD (click to make larger)
What you'll notice if you look at this carefully is that the top item lists Ergun's degrees as BA, MA, MDiv, MTh, DMin, PhD. However, the second link has them as BA, MA, MDiv, MTh, PhD. And, if you attempt to click on the screenshot, you get a 404 error as the PDF file that used to contain Ergun's very short biography has vanished.
However, once it ends up on the Internet, it's pretty much there forever. I can testify to that. And, in fact, you'll note in the same search other sites that have copied Ergun's old bio. For example, at this Worship Expo 2009 site we find:
It's the old bio, with the Campbell's Alphabet Soup of Educational Letters (BA, MA, MDiv, MTh, DMin, PhD)!
Here's another one, just to show that this is the biography that is currently being sent out. This Acts 1:11 conference is scheduled for Nov. 12-13, 2009 in Lawrenceville, GA and Ergun is a featured speaker. Here's his bio:

Again with the same OLD set of letters! (BA, MA, MDiv, MTh, DMin, PhD). In fact, you can tell they're just cutting and pasting the bio from Ergun's website, because it has the same error (Th,M instead of Th.M or ThM).

There's that DMin degree again but here's the first real mention, outside of the YouTube comment, of the Doctor of Theology (DTh) degree. And there's neither hide nor hair of the PhD Ergun's been claiming all this time. Is it possible this is the correct list of degrees?
Here's another piece of evidence. Back in 2003, when Ergun pulled up stakes from Criswell College to go to Liberty, Baptist Press ran an article which contained the following information: After receiving a B.A. from Cumberland College, Caner received the M.A. from The Criswell College, M.Div. and Th.M. from Southeastern Baptist Theological Seminary and completed a D.Min. at Emmanuel Baptist University and a D. Theol. at the University of South Africa.
There's that pesky DMin! From an outfit called "Emmanuel Baptist University." Interestingly, when I Googled this institution of higher education, the first thing that popped up was "Is Emmanuel Baptist University real?" Uh hunh. That gives me real confidence in this institution of higher "education." And, when I finally got to the "university's" website, I received the following pop-up:
I don't know about you, but this just about screams "watch OUT!" to me. This next screen with the history of the university, doesn't comfort me in the least:
And then there's the tuition, a bargain at $100 per credit hour!
Then there are the degrees, the process of which is measured out in "years," and in six "years" a person can have a terminal doctoral degree.
This is suspicious. Anyone who has done graduate-level work in the average American university knows that while one can usually predict that getting a Master's degree is going to take one year beyond the BA, that is by no means certain. And getting a PhD can take the better part of a decade, depending on the amount of work and writing one does on one's dissertation.
For example, a friend of mine spent a combined 10 years in classwork, fieldwork, exams, writing the thesis and the dissertation and finally defending the dissertation. I haven't asked him, but I suspect he might look askance at the idea that one could get a Doctor of [Some Religious Thing] one year after completing a Master's AND after the payment of $3,200, plus additional fees as required.
And finally, there are those accrediting agencies, which look to be about as reputable as a "university" that measures out time to completion of a degree in "years."

It appears that the first two "accrediting organizations" are fake. Here's what Steve Levicoff, who wrote a self-published book about fake Christian degree-granting outfits called Name It And Frame It?, had to say: "Claiming recognition by the American Accrediting Association of Theological Institutions and the American Accrediting Educational Association of Christian Schools, neither of which are legitimate agencies, the University of Biblical Studies (UBS) was originally founded in 1955 as "Modular Education." Their 22-page catalog states, "Participating colleges award Associate's, Bachelor's, Master's, and Doctor of Ministry Degrees," but they do not name the participating colleges." [emphasis added, but there's more at the link!]
There doesn't seem to be anything on the third outfit, the Southern Association of Christian Schools, in a search on the web, beyond schools that claim its accreditation. I suspect it's as bogus as the first two accrediting outfits.
If Caner got his DMin from an institution that promises credit for life experience, charges tuition far underneath what is the going rate for graduate education (if you've checked lately, even public universities are expensive!), grants a "doctorate" after one year's study beyond a master's degree and has bogus accrediting agencies, then I could see why he might want to hide this fact. However, let me be clear: I am not saying that Emmanuel Baptist University is a "diploma mill." However, it is apparently an unaccredited institution of something.
But what concerns me more is that Caner continues to claim that he has a PhD. As far as I can tell, he does not. He does have a ThD from the University of South Africa (Unisa), which is a distance university of many years' standing and which has graduated some highly distinguished alumni, including Desmond Tutu and Nelson Mandela. I'm not sure why Caner claims the PhD instead of the ThD. He can't make the argument that they are equivalent degrees, even if they are both academic degrees, because Unisa awards both the PhD and the ThD. If the intention was to get a PhD, then he could have gotten one there in the appropriate department. Instead, he got a ThD, and the information in the Liberty Baptist Theological Seminary catalogue reflects that.
