There are so many misunderstandings with the Qur'an that is spreading everywhere.
It's depending on how you see yourself. Knowing yourself is the interesting part. Let's say you have read the Qur'an and its tafsir, and let's say you are wrong to understand it. That's okay as long as you realize yourself as a human who seek the truth, Allah Subhanahuwata'ala has characteristic Allah is Al-Haadi, Allah will give you guidance as long as you do it in the name of Islam. And believe Allah Subhanahuwata'ala always seeing you, and always give you guidance, hearing your prayer.
Syaitan(Satan) has a characteristic; they are stubborn. Allah Subhanahuwata'ala told them to worship Adam, and Syaitan rejected it, and as a Muslim we have to get rid of that Syaitan characteristic in ourselves. Don't be stubborn; always realize that we are human and might be wrong sometimes, always pray to the god to give us guidance, forgive us if our deeds are wrong, and have a faith.
