Excellent.
There are several problems with your above comment. First of all you have made an assumption about what kind of content is found in the Qur'an and what kind is found in the Sunnah, but your assumption is false. The division between content is not based on 'more important' or 'less important'. Every teaching of Islam is significant. So this is not the point of distinction. Rather, as I mentioned numerous times in this thread, in general the fundamentals of the message of Islam and its guidance are found in the Qur'an, whereas the practical implementation, the laws, details and explanations, specific prophecies are found in the Sunnah.
Secondly, the hadith are not more strict than the Qur'an. I assume that you are thinking of penal law, but there is still no case where the hadith prescribe a more severe punishment than the Qur'an. They clarify the context and conditions of those punishments. Lastly, the Qur'an and Ahâdîth are taken together. We don't take from one instead of the other in some cases. We follow the Qur'an in light of the Ahâdîth NOT taking the Ahâdîth instead of the Qur'an.
Here but I'm sure you've alreadey seen this.
Where did you get this from?! The only way this can occur is in the case of apostasy in which case you were wrong in distinguishing it from the above.
No, they are not. God is Merciful, but He is Just. ANYONE who repents no matter WHAT they have done, they will be forgiven. THAT is God's mercy. God's punishment only comes upon those who persist in their misguidance and stubbornly refuse to repent. He has made it so easy for people to accept the truth but they still turn away and reject the bounties of God.
16:33 ...And in no way was God unjust to them, but rather they were unjust to themselves.
