I'm perplexed why you want to tackle the fact that your Bible disagrees with Jude's Bible on the fundamental issue of whether Hindus got to Hell - by referring to the Quran? I mean - where's the logic in that??
Uhm, maybe to show your conclusion is illogical.
Is being consistent with how you think really that perplexing?
Are you saying that the Bible is as unreliable as you imagine the Quran to be?
No, I'm asking if you believe the Koran to be as unreliable as you claim the Bible is.
I guarantee 99 out of 100 readers would understand this point.
As for the core beliefs of Muslims - I've stated them. If you choose to believe Muslims have other core beliefs or that Muslims don't believe these core beliefs - it is for you to show your proof to back up your beliefs about Islam.
So the issue of hell is not a core belief in the Koran but is in the Bible? Strange, how did you come to that conclusion?
