The parable of Qur’an is that of hobbled camels. If its owner attended to keeping their ropes tied, he keeps hold of them. But if he lets them loose, they go away.

How miserable for someone or some of you to says: I forgot such and such verse but, rather he was made to forget. So, keep attending to the Qur’an, for it escapes from the hearts of men faster than a camel from its fetter.

The Messenger of Allah said to me: Read the Qur’an in a month. I said: I can tolerate more than that, and I kept asking him until he said: Read the Qur’an in five days, and fast three days of the month. I said: I can endure more than that. He said: So fast the most beloved fasting to Allah; the fasting of David (PBUH). He used to fast one day and break his fast the next.
