Indeed, this Qur'aan is the banquet of Allaah...

Ibn Mas'ud رضي اللّه عنـه used to say: 

"Indeed, this Qur'aan is the banquet of Allaah; so take from it as much as you can [i.e. learn from it] for I know nothing more unworthy than a house in which there is nothing of the word of Allaah. The heart which contains nothing of the word of Allaah, goes to ruin like a house in which no one lives." - al-Darimi
