The importance of listening to the Holy Quran
The Quran was brought down upon the Holy Prophet (PBUH) in parts and not in whole. The intention of Allah in doing so was to make the Holy Prophet (PBUH) recite it in small portions to his followers and them to listen to it and absorb it in small portions. As they absorbed the portions of the Quran while they listened their faith in Allah and the last Prophet became stronger. And thus they followed Islam and became pure Muslims in every sense.
