One of the Salaf once said, "Everytime I increased upon my (daily) portion of Qur'aan, my time would increase in barakah (blessings). I kept on increasing up until my daily portion reached ten Juz' (a third of the Qur'aan)!"
Ibraaheem bin 'Abdil-Waahid al-Maqdisee said, whilst advising ad-Diyaa' al-Maqdisee who intended to go out on a journey to seek knowledge, "Recite much Qur'aan and never abandon it, for verily that which you want to learn will become easier in accordance with how much you recite."
ad-Diyaa' said, "So I noticed this and experienced it much. If I recited a lot of Qur'aan then listening to many Hadeeth and writing all of them down would be easy for me, and if I didn't recite then it would become difficult."
