Establishing That God Doesn't Lie
To add- if our fitrah wants the Lord to be all good, then it also wants him to be all kind. I wouldn’t like to be punished even if I am in the wrong. An all kind person would forgive me unconditionally. So there should be no hell. But how is my fitrah the scale- God is just and kind and only he can keep the two in balance perfectly. What does my fitrah have to do with this?
I do agree that the Quran shows God to be all good. But what does my fitrat have to do with ascertaining whether all of it is truth?
