Every person should be responsible for their sin. Even if one man wants to take all the punishment for it, that wouldn't be justice would it? The other guys get away with it as long as they believe that the man saved them from their punishment. The worst that can happen to them is go to a purgatory. Right? I don't see the justice in that.
Now let's review Muhammad's claim that Allah will punish Christians and Jews for the sins of Muslims:
Sahih Muslim 6666—Allah’s Apostle said: No Muslim would die but Allah would admit in his stead a Jew or a Christian in Hell-Fire.
Sahih Muslim 6668—Allah’s Messenger [said]: There would come people amongst the Muslims on the Day of Resurrection with as heavy sins as a mountain, and Allah would forgive them and He would place in their stead the Jews and the Christians.
According to Kim, these passages mean that Muslims accumulate many "minor sins" throughout their lives, ultimately producing a "mountain" of sins. Thus, Muhammad declares that Allah will punish Christians and Jews for the mountainous "minor sins" of Muslims. But wait a minute! Kim says that "every person should be responsible for their sin." This means that, according to Kim, Allah is immoral and unjust, and Muhammad is an evil deceiver for proclaiming such a wicked deity!
But wait, there's more! According to Kim, Muhammad can't communicate clearly. The quotations from the Hadith are clear and self-explanatory. However, Kim holds that Muhammad's words in the Hadith can't be understood without commentaries! Muslim commentators, then, are better communicators than Muhammad. Why, then, did Allah send a prophet who can't say what he means? Kim wrote:
And if anyone is going to paste Hadith on here, give me as much commentary on it as possible, if you can. Otherwise you are misunderstanding it and misrepresenting it. I just realized how badly David misrepresented the first two hadiths after I read the commentary on it :)
Notice that I "misrepresented" the Hadith by assuming that Muhammad means what he says. Unfortunately, I've never understood the Muslim exegetical principle that Allah and Muhammad often say the opposite of what they mean. Silly me!
Well, I'm calling you out, Kim. Give us the commentary on the Hadith that tells us what Muhammad "really" meant when he said that Allah will punish Christians and Jews for the sins of Muslims.
In the meantime, let's all think about how the simple, easy-to-understand "Religion of Peace" works. Allah sends the Qur'an, and Allah says that the Qur'an is perfectly clear and free of imperfections. Nevertheless, Muslims tell us that the Qur'an cannot be understood apart from the Hadith. So we go to the Hadith, and we find that Muhammad's clearest statements cannot be understood apart from the writings of Muslim commentators. But Muslim commentators contradict each other all the time, so it seems that we just can't understand Islam! And Kim says she's confused about Christianity!
