One of the Pious Predecessors and Successors said:

“Everytime I increased [reciting] my [daily] portion of the Qur’ān; blessings increased in my time, [so much so] that I kept on increasing my daily portion, until I read ten parts [a third of the Qur’ān].”

Dhayl Tabaqāt al-Hanābilah 3/205 | Al-Imām ibn Rajab [may Allāh have mercy on him]
