Mukhtasar Bukhari (Abridged) 1820 — Memorizing the Quran and reciting

Narrated Abdullah bin Mas'ud (may Allah be pleased with him): The Prophet (peace and blessings of Allah be upon him) said: "It is bad that any of you says, 'I have forgotten such-and-such verse.' Rather, he should say, 'I have been made to forget it.' And keep reciting the Qur'an, for it escapes from the hearts of men faster than camels do."
