When you don't know Quran don't write about it.
muhammed was the last prophet but not the last messenger.
Based on Muhammad’s statement that there were 124,000 prophets and 313 of them were messengers (see the commentary by Al-Zamakhshari), the classical understanding is that messengers are a special subgroup of prophets, and their distinction was that they came with new revelation, a book, a new law, but the prophets only warned the people and merely pointed back to an already existing law. Yet this understanding is contrary to what the Quran actually says, since it repeatedly connects prophets with the scriptures that were given to them.
The Quran teaches that Muhammad is the seal of the prophets, with the implication being that he is the last prophet:
Muhammad is not the father of any man among you, but he is the messenger of Allah and the Seal of the Prophets; and Allah is ever Aware of all things. S. 33:40 Pickthall
Muhammad is not the father of any of your men, but he is the Apostle of Allah and the Last of the prophets; and Allah is cognizant of all things. S. 33:40 Shakir
Note, however, that this verse does not say that he is the last messenger, or the seal of apostleship. That will become important in this discussion.
The Quran distinguishes between a messenger and a prophet:
Never did We send a Messenger or a Prophet before you, but; when he did recite the revelation or narrated or spoke, Shaitan (Satan) threw (some falsehood) in it. But Allah abolishes that which Shaitan (Satan) throws in. Then Allah establishes His Revelations. And Allah is All-Knower, All-Wise: S. 22:52 Al-Hilali & Khan
Was Muhammad the Last Messenger?
exactly which strain of islam is the "right" islam? and how gets to decide that? Every sect interprets the same holy books and comes up with different explanations for the same set of rules. Who gets to decide which is right? And who gets to decide that that "wrong" ones should be killed?
