A brief comment before watching the debate:
NO NEW PROPHET
Allah never said that another prophet would come after Muhammad (S) dies. Nowhere does the Qur'an tell us to believe in any future prophets.
3:144 Muhammad is only a Messenger. The Messengers before him have passed on. So, if he died or were slain, would you turn about on your heels? But anyone who turns about his heels, would not, in the least, harm God. And God will soon reward those who remain appreciative (for the guidance).
33:40 Muhammad is not the father of any man among you, but he is God’s Messenger and the Closing Seal of all Prophets. God is Knower of all things.
3:55 God said, “O Jesus! I will cause you to die of natural causes, I will exalt you in My Sight and will clear you of the slander of the disbelievers. And I will cause those who truly follow you to dominate those who reject, until the Day of Resurrection. Eventually, all of you will return to Me. Then I will judge among you about that wherein you used to differ.” [Wafaat = Dying of natural causes. Rafa’ = Exalt = Raising in honor. Ilayya = allegorically, in My Sight]
4:158 Nay, God exalted him in His Sight. God is Almighty, Wise. [They had plotted thinking that crucifixion was a death of curse. But God raised him in honor. See 3:55]
