حَدَّثَنَا يَحْيَى بْنُ يَحْيَى ، قَالَ : قَرَأْتُ عَلَى مَالِكٍ ، عَنْ نَافِعٍ ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَ : " إِنَّمَا مَثَلُ صَاحِبِ الْقُرْآنِ كَمَثَلِ الإِبِلِ الْمُعَقَّلَةِ ، إِنْ عَاهَدَ عَلَيْهَا أَمْسَكَهَا ، وَإِنْ أَطْلَقَهَا ذَهَبَتْ " ،
'Abdullah bin '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.
