Mukhtasar Muslim

`Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) reports that` the Messenger of Allah (peace and blessings be upon him) said: The worst among you is the one who says, "I have forgotten such and such verse." Rather, he should say, "I have been made to forget." And take care of the Qur'an and remember it, for it escapes from people's hearts faster than a tied camel is released.
