The shahada, the oath we take upon becoming a Muslim, is that there is no God but Allah and Mohammed is his final messenger. So no, there will be no more prophets for whatever time remains of this universe. This is the teachings of Islam.
My question to you still stands, what is your purpose on this board? While we are welcoming to healthy debate we do not need someone telling us what "flaws" they feel our religion has, Muslims are hugely flawed but Islam is not. You argue for homosexual polygamy and women marrying multiple men, this is not the purpose of this board. If you have true question about this religion then we are very receptive to them. But if you want to argue for the sheer sake of argument then you are wasting your time. Argueing against the Quran's teachings to a Muslim is like argueing against gravity, we simply will not be convinced by that it is not true. Feel free to read a Quran, there are online versions open to anyone. But know this, Allah guides whom He pleases and pushes away others...if you cannot be guided then there is nothing we can do. Our jobs are to be submissive (to Allah) and follow His decree. (The Quran)
