"Qur'an escapes from memory faster than a camel from its ropes"

The Prophet S.A.W.S said,

"Read the Qur'an regularly. By the One in Whose Hand Muhammad's soul is, it escapes from memory faster than a camel does from its tying ropes.''
[Al-Bukhari and Muslim]

Commentary: To safeguard the Qur'an means to recite it regularly, because if one fails to do so, he tends to forget it quickly. In the absence of regular recitation, one is bound to forget it more quickly than a camel breaks loose bound with. The breaking loose by the camel to liberate itself is a simile for the quick process of forgetting.
