Sahih Muslim, 1839

Abdullah b. 'Umar reported Allah's Messenger (ﷺ) as saying:The example of a man who has memorised the Qur'an is like that of a hobbled camel. If he remained vigilant, he would be able to retain it (with him), and if he loosened the hobbled camel it would escape

Rapporté par Abdullah ibn Umar رضي الله عنه : Le Messager d’Allah ﷺ a dit : « L’exemple de celui qui a mémorisé le Coran est comme celui d’un chameau attaché. S’il reste vigilant, il le garde, mais s’il le relâche, il s’enfuit. »
