It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "It is very bad for any of you to say, 'I forgot such and such verse,' (rather, one should say) 'I was made to forget.' And keep reciting the Noble Qur'an, for its slipping away from the hearts of people is swifter than the escape of a camel."
