181. Chapter: On the command to continue reciting the Qur'an and being careful not to allow oneself to forget it

1002. Abu Musa reported that the Prophet, may Allah bless him and grant him peace, said, "Make a habit of reciting this Qur'an. By the One in whose hand the soul of Muhammad is, it slips away free quicker than a camel gets loose from its hobble." [Agreed upon]

1003. Ibn 'Umar reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "The metaphor of someone who knows the Qur'an is that of a hobbled camel. If he attends to it, it stays with him. If he lets it go, it wanders away." [Agreed upon]
