How can you avoid sinning in Ramadan? There are locks upon the hearts, sins that prevent the heart from benefiting from the Quran. 

The Quran is sent to protect the human heart. The heart was chosen as the landing platform of the Quran. If the heart is not ready to receive it then the fruits from the Quran will not grow!

The heart has to go through major changes and we have to identify those locks. These locks need opening up so we can make ourselves better.
