Yes that's right, any other questions your unsure with? 
Yes I do.
Is it true that Muslims believe that of all the descendents of Adam who have ever lived and existed, 99 out of every 100 will go to Hell in the Afterlife?
And for the sake of argument hypothetically, let’s say that you’re right, that the one and only Abrahamic God (no trinity) somehow really does exist and that somehow Islam is the one true religion and that the Bible had originally been the word of God however that it got corrupted over time. If this is really the case why do you think He would let so many people go astray? How is this fair?
I know many good people on ATARnotes who donate to charity and live their life through helping people, why should they be denied the privilege of going to Heaven? And furthermore why is it so important to believe in the existence of God and the legitimacy of the prophet Mohammed? How do you know he wasn’t just a regular person and was just lying about all this stuff (no offence)?
Good question

.
Well as a muslim i cant really judge who goes hell and who goes heaven. But if you deny the exsistance of the creator then I think you'd be going to hell. But I mean honestly, how can someone deny the exsistance of the creator, how'd we all come into exsistance ..say big bang for example.. then how was everything designed, who made the first particle..
so u agree theirs a creator. right.
Also u said about the people some being good people and going to hell ... well i can't really tell u, its unclear.. but some people are going to hell and others to heaven depending on their actions what they did, etc... btw i'm referring this in the sence that people believe in god, such as a relijion like judaism or christainity, and practice their relijion and pray and give charity etc... but people who deny the exsistance of god, its hard to say what happens to them, but i presume hell.
No one is denyied the prevalge of going to heaven, except the ignorant, i've told some aethist freinds of mine,.."dude believe in one god".. but they dont want to, they think they'll die and it all ends.. (ofcouse not..theirs something after death, then whats the point of this life?) .. muslims believe that this life is to worship god, and to be good to people etc.. (terrorism is nothing to do with islam... its just incorrect interpretation of verses of quotes from the prophet and the several quran verses)
And about ur last point that Muhammed was a regular person, well their were signs of prophethood in him.. the first of this was the book the quran, it was written in such a complex arabic scripture that everyone at the time knew it was not something a human could do. for more visit ;
http://www.islaam.com/Article.aspx?id=61^ he also had several miracles...
also i want to ask u som questions; tell me
if god doesnt exsist, how designed the universe, a plant, photothensis's, how our body works etc...
why are we living now?... for what purpose?
what happens when we die?
would someone who killed hundreds thousands if not millions like hitler or saddam, or osama, go to heaven (i'd say unfair)
i'm actually happy ur discussing this with me

.. i like to see people interested more in the truth.
also, if theirs a relijion better than islam, please tell me, interested to check it out.
