The intro has the same line about growing up in Columbus and having a mosque-building father (which has already been discussed here). Ankerberg says that "their family disowned them," (1:44) which we could ask Ankerberg to justify - the justification would seem to be that their non-custodial father disowned them.
Ergun seems to insist that that Shahada says that Mohammed is "his final seal of the prophets" or "the final prophet." While that is doubtless the Sunni view of Mohammed, the literal translation of portion of the Shahada about Mohammed is just "... Mohammed is the messenger of Allah."
One important point that is presented is the fact that Mohammed is described in the Koran as being an example for Muslims:
Surah 33:21 Ye have indeed in the Apostle of Allah a beautiful pattern (of conduct) for any one whose hope is in Allah and the Final Day, and who engages much in the Praise of Allah. (YUS)
However, if one attempts to have as many wives as Mohammed, one will run smack into the limitation of four wives that is present in Islam. Likewise, if one attempts to prevent ones widows from marrying, one will run afoul of Islamic law.
Ergun raises the idea (around 5:30 into the clip) that Mohammed says in the Hadith that "he" was spiritually married to Mary. The apparent source for this is the following, as taken from the Caners' book, "Unveiling Islam":
"Oh Khadija, know that God has wedded me to Mary, Christ's mother in paradise." HE repeated this to Aiysha, "Oh Aiysha [sic], didn't you know that God Almighty in heaven has wedded me to Mary, the daughter of Imran, to Kulthum, Moses' sister and to Assiya, wife of the Pharoh."7(pp. 136 and 141, "[sic]" is in the book - note that the book is not necessarily the Caners' own writing - the chapters are allegedly written by various women)
7. Related by Abu Umama in later ahadith.
I tried to track down a better citation for this alleged narration. I found an article by Salman Hassan Jabbar, dated to 1994, which states:
Also worth mentioning in this connection is that Muhammad will have the lion's share of all the good things in paradise for surely he was singled out for favor by God by virtue of his flight into the seven heavens (Al Isra'a wal Mi'raj incident) It was there too that he received from God's hand all the teachings which he transmitted to his followers. When he returned to earth from that trip he was unable to hide the fact from his first wife, Khadija - the eldest. He told her as she lay dying: "Oh Khadija, know that God has wedded me to Mary, Christ's mother in paradise." He repeated this story to his favorite wife, Aiysha, after the Hejira, saying:" Oh Aiysha, didn't you know that God Almighty in heaven wedded me to Mary the daughter of Imran, to Kulthum, Moses' sister and to Assiya, wife of the Pharaoh". (related by Abu Umama)Abu Umama was one of the companions (sahaba) of Mohammad. That said, I was not able to verify this supposed hadith from either Bukhari's collection of hadith or Muslim's collection of hadith.
With a little more digging, I found an interesting response from Rasheed Gonzales (link to response) to use of this narration. In relevant part, Rasheed writes:
(see the remainder of Rasheed's post, for the argument from this quotation, but the gist of the argument is that the chain of narration is weak, and it is possible that this hadith is actually ancient Christian propaganda, designed to make Muslims appear [even more?] despicable to Christians.)Let us now take a look at what Ibn Kathîr said in his exegesis of the above mentioned verse (66:5) in his Tafsîr al-Qur'ân al-'Adhîm. Ibn Kathîr mentions,In his al-Mu'jam al-Kabîr, Abul-Qâsim at-Tabarânî said,Abū Bakr bin Sadaqah narrated to us: Muhammad bin Muhammad bin Marzūq narrated to us: 'Abdullah bin Umayyah narrated to us: 'Abdul-Quddūs narrated to us from Sâlih bin Hayyân, from Ibn Buraidah, from his father: [concerning] «widows and virgins» (66:5), [who] said, "In this verse, Allah promised His prophet, may Allah send salutations and peace upon him, that He would marry him to the widow: Âsiyah, wife of Pharaoh, and with the virgins: Mary bint 'Imrân."In his biography of Mary, peace be upon her, Hâfidh Ibn 'Asâkir mentioned from the route of Suwaid bin Sa'îd: Muhammad bin Sâlih bin 'Umar narrated to us from ad-Dahhâk and Mujâhid, from Ibn 'Umar, he said,Gabriel came to Allah's messenger, may Allah send salutations and peace upon him, at the death of Khadîjah and said, "Surely, Allah greets her with peace and gives glad tidings of a house of pearls in Paradise, distant from the fire, containing no hardship, nor noise, of hollow pearls between Mary bint 'Imrân's house and Âsiyah bint Muzâhim's house."And from the hadîth of Abî Bakr al-Hudhalî, from 'Ikrimah, from Ibn 'Abbâs that the Prophet, may Allah send salutations and peace upon him, entered upon Khadîjah while she was dying and said, «O Khadîjah, if you meet your co-wives, then greet them with peace from me.» She said, "O Allah's messenger, have you married before me?" He said, «No, but Allah will marry me to Mary bint 'Imrân, Âsiyah wife of Pharaoh, and Kulthum sister of Moses.» [It is] weak also.Abū Ya'lâ said,Ibrâhîm bin 'Ar'arah narrated to us: 'Abdun-Nūr bin 'Abdillah narrated to us: Yūnus bin Shu'aib narrated to us from Abî Umâmah, he said, 'Allah's messenger, may Allah send salutations and peace upon him, said, «I have learned that Allah married me in Paradise to Mary bint 'Imrân, Kulthum sister of Moses, and Âsiyah wife of Pharaoh.» So I said: [be it] a pleasure for you, O Allah's messenger!'
At around 8:15 into the clip, Ergun provides an amusing soundbite, "Fine, I don't like half the Christians I know." His point was that it is not Christians who are the reason for us to be Christians, it is Christ. That point is valid and good, even though the statement itself is itself a little amusing and somewhat sad, given our experience with him.
