Here is my latest debate and a summary of my presentation. I plan to publish it as a booklet in the future.
THE REASONS THE QURAN GIVES FOR MUHAMMAD BEING A PROPHET
Reason 1 - If Muhammad was not a true prophet God would strike him dead.
And if the apostle (Muhammad) were to invent any sayings in Our (God’s) name, We should certainly seize him by his right hand, And then certainly should have cut off his life artery (Aorta). (Qur'an 69:44-46, Yusuf Ali)
Narrated (told by) `Aisha: The Prophet (Muhammad) in his ailment in which he died, used to say, "O `Aisha! I still feel the pain caused by the food I ate at Khaibar, and at this time, I feel as if my aorta is being cut from that poison." (Sahih al-Bukhuri: vol. 5, bk. 59, no. 713; 4428)
Reason 2 - Muhammad is a prophet because the Qur’an is in clear Arabic. (Not presented in the debate due to limited time.)
In truth We (God) know that they (Muhammad’s opponents) say, “It is only a mortal who is teaching him.” The speech of the one at whom they hint is foreign, whereas this (the Qur’an) is clear Arabic speech. (Qur’an 16:103, 44:14, Jones)
Reason 3 - There are no contradictions in the Qur’an
Do they not consider the Qur'an (with care)? Had it been from other than God, they would surely have found in it much discrepancy. (Qur’an 4:82, Yusuf Ali)
Reason 4 - Bring a sura/chapter like it.
Or do they say, “He (Muhammad) has invented it (the Qur’an)”? Say (to them): “Then bring a sura like it; and call on those you can apart from God, if you are truthful.” (Qur’an 10:38, Jones)
Say, “Then bring a Scripture from God that gives you better guidance than the two of them (Torah and Qur’an), and I shall follow it, if you are telling the truth.” (Qur’an 28:49, Jones)
Reason 5 - The Qur’an confirms the earlier scriptures.
O you People of the Book! Believe in what We have (now) revealed (the Qur’an), confirming what was (already) with you. (Qur’an 4:47, 46:12, Yusuf Ali)
Reason 6 - Muhammad is foretold in the Bible.
Those who follow the messenger (Muhammad), the prophet of his community, whom they will find mentioned in the Torah and the Gospel in their possession. (Qur’an 7:157, 61:6, Jones)
If you know of any other reasons the Qur'an gives please post them in the comments.
A BIBLICAL ASSESSMENT
Reason 1 - Sura 33 - The Ungodly Privileges of Muhammad
Qur'an 33:4 and 37 - Zaynab
Qur'an 33:50 - Any woman he wants.
Qur'an 33:51 - Not equal time with wives.
Narrated Aisha: ... (Quoting Quran 33:51) ... I said (to the Prophet), "I feel that your Lord hastens in fulfilling your wishes and desires." (Sahih al-Bukhari: vol. 6, bk. 60, no. 311)
Reason 2 - Muhammad turns people away from reading the prophets.
