From the greatest of causes for the uprightness of the heart and its protection [from harm] is the plentiful reading of the qur.aan.
Whoever does not possess a determination for [anything] other than [fulfilling the desires of] his stomach and his private parts, then he is considered from amongst the beasts…
By Allaah, were the hearts sound (pure), they would be saddened at missing out [from goodness to be attained]. How many are the hours which pass by us, and we are prevented from benefitting from them?
If they entered Makkah, they would like to not leave until they had completed reading the Qur.aan [in full] there.
