Ahmed: You wrote that it is forbidden for Muslims to kill, oppress, or do injustice to their fellow human beings.
However, the problem is, is that you now have a contradiction in your beliefs.
What was written above was very clear, Mohammed GUARANTEED that anyone chaste sexually and with his speech, was GUARANTEED heaven. He said nothing in this statement regarding murder disqualifying you from this guarantee, so long as you are chaste with your private parts and your tongue.
Under those standards, either you would have to accept that such a monster as Jack The Ripper is guaranteed to get into heaven, or else Mohammed was mistaken when he made that statement.
If Mohammed made other statements elsewhere about murder disqualifying one from heaven, then those statements contradict this one. In which case Mohammed is contradicting himself, at least one of his statements would be incorrect, and you still have a contradiction in your religion.
Hmmm really interesting.
It could be logic if it was in the context but unfortunetly it is not.
Certain things are Haraam in Islam like:
certain behaviours, such as adultery or abuse, abstention in the general elections (e.g. in Indonesia) and profane language.
certain objects and sacrilege.
certain foodstuffs or food ingredients, such as alcohol or pork.
and also to foods, objects and people that would normally be halaal but which were tarnished in some or other way, for example meat slaughtered in a non-permitted way or people with certain sexual preferences.

Now with that in mind, all these things were probably exposed by Muhammad (pbuh) before he said this statement. Knowing this it is clear that the meaning behind the statement of Muhammad is. "If you avoid lies, backbiting, haraam food and illegal sexual acts you would go to Paradise. But if you kill somebody you won't go to Paradise even if you do all these good things."
It some simple logic.
Reading your post it looks like you're just a troll trying to bash Islam my friend.
Saying that Muhammad contradicted himself like that is an insult in my eyes and I'm not even Muslim. Imagine how it is in the eyes of a Muslim.
You know the true meaning of this: Prophet said, "Whoever guarantees me (the chastity of) what is between his legs (i.e. his private parts), and what is between his jaws (i.e., his tongue), I guarantee him Paradise." [Bukhari #799]. Don't try to act smart friend. We're no child anymore, starting fights are useless.
